(Quality Points for Student’s Grades) Write a function toQualityPoints that inputs a student’s average and returns 4 it’s 90–100, 3 if it’s 80–89, 2 if it’s 70–79, 1 if it’s 60–69, and 0 if theaverage is lower than 60
(Perfect Numbers) An integer number is said to be a perfect number if its factors, including1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 =1 + 2 + 3. Write a function isPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect.Challenge the power of your computer by testing numbers much larger than 1000.
(Perfect Numbers) An integer is said to be a perfect number if the sum of its divisors, including 1 (but not the number itself), is equal to the number. For example, 6 is a perfect number, because 6=1+2+3. Write a functionisPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the divisors of each perfect number to confirm that the number is indeed perfect.

- (a) Write the following functions and their docstrings: • between (num1, num2, num3) takes 3 integer arguments and returns True if num2 is between num1 and num3. It is not between them if it is equal to either of the other two. For example, given the inputs 5, 3 and 0, the value returned should be True. Given the inputs -2, 2 and 2, False should be returned. Note that there is no restriction that num1 must be less than num3. • majorityEven (num_list) returns True if more than half of the integers in the num_list are di- visible by 2, with no remainder, otherwise it returns False. The list can be of any size. Recall that zero is divisible by 2 with no remainder. For example, the function should return False for the list [1,2,3,6] (as only two of the four numbers are divisible by 2) and True for the list [0,1,-4] (as two of the three numbers are divisible by 2). (b) Generate at least six test cases for each function you wrote in part (a). You may use white-box and/or black-box test case…arrow_forward4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. Write a function called isPrime that receives an integer and determines whether the integer is prime or not. Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forwardCall main and run all of the functions. Not: Write some print functions to see the outputs inside each function. (Python programming language)arrow_forward
- (Square of Asterisks) Write a function that displays a solid square of asterisks whose side isspecified in integer parameter side. For example, if side is 4, the function displays: **** **** **** ****arrow_forward: Write a function that adds two numbers. You should not use+ or any arithmeticoperators.arrow_forward(Rounding Numbers) An application of function floor is rounding a value to the nearestinteger. The statementy = floor(x + .5);will round the number x to the nearest integer and assign the result to y. Write a program that readsseveral numbers and uses the preceding statement to round each of these numbers to the nearestinteger. For each number processed, print both the original number and the rounded number.arrow_forward
- (Rounding Numbers) Function floor may be used to round a number to a specific decimal place. The statement y = floor(x * 10 + .5) / 10; rounds x to the tenths position (the first position to the right of the decimal point). The statement y = floor(x * 100 + .5) / 100; rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines four functions to round a number x in various ways a) roundTolnteger(number) b) roundToTenths(number) c) roundToHundreths(number) d) roundToThousandths(number) For each value %3D read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hun- dredth, and the number rounded to the nearest thousandth.

The statement y = floor(x * 10 + .5) / 10; rounds x to the tenths position (the first position to the right of the decimal point). The statement y = floor(x * 100 + .5) / 100; rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines four functions to round a number x in various ways a) roundToInteger(number) b) roundToTenths(number) c) roundToHundreths(number) d) roundToThousandths(number) For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hun- dredth, and the number rounded to the nearest thousandth. IN C PROGRAMMING LANGUAGE PLEASEarrow_forward(Single Digit) Complete the definition of the following function:singleDigit :: Int -> Int singleDigit takes a positive integer, num, as input and returns a digit between 0 and 9 as the output. The output is computed as follows: sum all the digits in num to obtain a result; if this result is less than 10 then result is the answer; otherwise take the result and apply the same procedure (i.e. sum its digits and compute a result, and so on). Here is a sample run:*Main> singleDigit 37425 3 *Main> singleDigit 9876543 6 Here is how the above answers are computed by hand:singleDigit 37425 => 3+7+4+2+5 = 21 => 2+1 = 3 singleDigit 9876543 => 9+8+7+6+5+4+3 = 42 => 4+2 = 6arrow_forward
- (Exponentiation) Write a function integerPower(base, exponent) that returns the value ofbaseexponentFor example, integerPower(3, 4) = 3 * 3 * 3 * 3. Assume that exponent is a positive, nonzero integer, and base is an integer. Function integerPower should use for to control the calculation. Donot use any math library functions.arrow_forward(Python)Write a function that receives an integer. The function must return a string containing thehexadecimal representation of the integer.arrow_forward(Displaying a Square of Any Character) Modify the function created in Exercise 5.19 toform the square out of whatever character is contained in character parameter fillCharacter.
