Suppose the count function for a string didn’t exist. Define a function that returns the number of non-overlapping occurrences of a substring in a string.
Answers
Answer:
I am writing a Python program:
import re
def NonOverlapping():
string = input("Enter a string: ")
substring = input("Enter a substring to find its non-overlapping occurances in " + string +": ")
occurrences=len(re.findall(substring,string))
return occurrences
print("The number of non-overlapping occurrences: " , NonOverlapping())
Explanation:
I will explain the program line by line.
import re this is the module for performing regular expressions matching operations in Python.
def NonOverlapping(): this is the function definition. The function name is NonOverlapping and this function returns the number of non-overlapping occurrences of a substring in a string.
string = input("Enter a string: ")
substring = input("Enter a substring to find its non-overlapping occurances in " + string +": ")
The above two statement ares used to take input from the user. First the user is prompted to enter a string and the string is stored in string variable. Next user is asked to input the substring and its stored in susbtring variable.
occurrences=len(re.findall(substring,string)) This is the main line of the function. It has two methods i.e. len() and re.findall().
The re.findall() method returns all non-overlapping matches of substring in string. The string is checked for the given substring from left to right and all the non-overlapping occurrences of the substring are found and a list of matches is returned. len() method is used to return the length of the string but here it is used to count the number of non-overlapping occurrences substring in a string which are returned by re.findall() method. The whole result of these two methods is stored in occurrences.
return occurrences This statement returns the number of non-overlapping occurrences of a substring in a string computed in the above statement.
print("The number of non-overlapping occurrences: " , NonOverlapping())
This statement displays the result by calling NonOveralling() method.

Which of the following is an INCORRECT statement regarding email contracts? A. Contracts completed via email are referred to as electronic mail contracts, or email contracts. B. Many contracts are now completed via email. C. Traditional challenges to the enforcement of a contract, such as fraud, duress, intoxication, and insanity may be asserted against the enforcement of an email contract. D. Email contracts are unenforceable unless accompanied by a traditional, written contract. E. Email contracts are enforceable as long as they meet the requirements necessary to form a traditional contract, including agreement, consideration, capacity, and lawful object.
Answers
Answer:
D. Email contracts are unenforceable unless accompanied by a traditional, written contract.
Explanation:
A contract is simply an agreement between two mutually consenting parties. With the advent of technology, electronic mail contracts, shortened as Email contracts are recognized by law so long as they have the attributes of contracts. So when there is an agreement between two parties, using the email platform, the law recognizes such.
Signatures do not have to be appended to validate these types of contracts, rather, a statement specifying that an agreement is a valid contract, and endorsed by the two parties, can be substituted for a signature. So far as all the elements of contracts such as an agreement, consideration, capacity and lawful object are adhered to, an email contract is as good as a written contract.
the function looks at each element in the atomic vector and sees if it can coerce them into integer or floating- point values. the function outputs a list that has separated the values into a list with integers, doubles, and character values. if the optional argument sort is true, then it will sort the results of each vector. For example, if x is the following vector, x <- c("house", "6", "2.2", "a", "3.4", "1") Then the output of by_type(x) will be a list:
$integers
[1] 6 1 1
$doubles
[1] 2.2 3.4
$character [1]
"house" "a"
Answers
Atomic vectors typically come in four different types: logical, integer, double, and character. Complex and raw are the two less common varieties.
An atomic vector can have any properties, with the exception of a dimension attribute, and is either logical, integer, numeric, complex, character, or raw (like matrices). For example, a matrix or NULL are not atomic vectors, but a factor is. This is, in essence, the same as is. atomic. Using the built-in int function, one can transform texts in Python into integers. Any Python data type can be sent to the int() function to be transformed into an integer.

For my c++ class I need to complete this assignment. I've been stuck on it for a few hours now and was wondering if anyone could help me out by giving me some hints or whatever.
You work for an exchange bank. At the end of the day a teller needs to be able to add up the value of all of the foreign currency they have. A typical interaction with the computer program should look like this:
How many Euros do you have?
245.59
How many Mexican Pesos do you have?
4678
How many Chinese Yen do you have?
5432
The total value in US dollars is: $1378.73
Think about how to break this problem into simple steps. You need to ask how much the teller has of each currency, then make the conversion to US dollars and finally add the dollar amounts into a total.
Here is a sketch of the solution.
double currencyAmount;
double total;
// get the amount for the first currency
total += currencyAmount;
// get the amount for the second currency
total += currencyAmount;
// get the amount for the third currency
total += currencyAmount;
// output the total
Notice the use of the += operator, this is a shortcut that means the same thing as total = total + currencyAmount. It is usful for accumulating a total like we are doing here.
Submit only the .cpp file containing the code. Don't forget the code requirements for this class:
Good style: Use good naming conventions, for example use lower camel case variable names.
Usability: Always prompt the user for input so they know what to do and provide meaningful output messages.

Example: Find the total sum of prime numbers from 1 - 100 The total sum is 1060. Verify your answers.
Answers
Answer:
The attached file is a C program that does much of what you want. It does not output the the sum of the primes, but lists the primes. The output is simple enough to change. This program builds quite easily with GCC.
I don't know what language you're using, so I'm just providing a piece of code I've written that might help you out.
Also:
There are a few tricks in searching for prime numbers. Here are some that I always like to take into account.
1) With the exception of 2 and 3, all primes are one away from a multiple of six
2) When testing a number for divisibility, you only have to test up as far as its square root.
3) You don't need to test for divisibility by composite numbers. Only prime factors are needed. Any composite numbers smaller than x will be multiples of primes smaller than x.
So you can very rapidly find primes with a loop that starts at 6, and goes up to whatever limit you want, incrementing by 6. Let's call the number of that loop x. You then only have to test if the x - 1 is prime and if x + 1 is prime. That eliminates 2/3 of the iterations needed. Also, when you find primes, put them in an array. I would start by creating an array with the numbers 2 and 3 already in it (those being the only two primes that are not adjacent to a multiple of six). Then each number tested only needs to be checked for divisibility by numbers in that array that are less than or equal to the square root of the number being tested. If the number is composite, then it is only divisible by something larger than its square root if it is also divisible by something smaller than its square root.
With all of this big blurb written, and some hard-to-read C code attached, if you're just looking to write something quick to do your homework, and don't care about it being efficient, you can just do something like this javascript style example:
var n, tally = 0, list = [], isPrime;
for(n = 2; n < 100; n++){
isPrime = 1;
for(m = 0; m < list.length && list[m] <= Math.sqrt(n) && isPrime; m++){
if(n % list[m] == 0) isPrime = 0;
}
if(isPrime){
list[list.length] = n;
tally += n;
}
}
console.log('sum of primes: ' + tally);
I haven't run that code, so do watch out for any errors I missed. Good luck!

Can someone help me with the following logical circuit, perform two actions. FIRST, convert the circuit into a logical
statement. SECOND, create a truth table based on the circuit/statement. (20 pts. each for statement and
truth table.
Answers
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.
Given the logical circuit, we are required to perform two actions on it. Firstly, convert the circuit into a logical statement. Secondly, create a truth table based on the circuit/statement. Let's understand how to do these actions one by one:Conversion of Circuit into Logical Statement.
The given circuit contains three components: NOT gate, AND gate and OR gate. Let's analyze the working of this circuit. The two input variables A and B are first passed through the NOT gate, which gives the opposite of the input signal.
Then the NOT gate output is passed through the AND gate along with the input variable B. The output of the AND gate is then passed through the OR gate along with the input variable A.We can create a logical statement based on this working as: (not A) and B or A. This can also be represented as A or (not A) and B. Either of these statements is correct and can be used to construct the truth table.
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
In the truth table, we have all possible combinations of input variables A and B and their corresponding outputs for each component of the circuit.
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.
