Given two variables A and B, with integer values, write an algorithm that changes the values of the variables, without creating a new variable.ex: A = 3, B = 5 -> A = 5, b = 3)
Suppose that the first number of a sequence is x, where x is an integer. Define a0= x; an+1=an/2 if an is even; an+1= 3*an +1 if an is odd. Then there exists an integer K such that ak=1. Write a Program that prompts the user to input the value of x. The program outputs the integer K such that ak=1 and the numbers a0, a1, a2,……….., ak.. (For example, if x=75, then K=14, and the numbers a0, a1, a2,……….., a14, respectively, are 75,226,113,340,170,85,256,128,64,32,16,8,4,2,1. )
Enhance your program from part a by outputting the position of the largest number and the largest number of the sequence a0, a1, a2,……….., ak.. (For example, the largest number of the sequence 75,226,113,340,170,85,256,128,64,32,16,8,4,2,1 is 340 and its position is 4. )
Write a program that inputs a number and checks whether it is a perfect number or not. A perfect number is the number that is numerically equal to the sum of its divisors. For example, 6 is a perfect number because the divisors of 6 are 1, 2, 3 and 1+2+3=6

- Python Starting with the right-most digit and moving to the left, determine the sum of every alternating digit. For the credit card “4833 1200 3412 3456”, we would sum 6 + 4 + 2 + 4 + 0 + 2 + 3 + 8 = 29. Double each of the digits not included in the previous step and then add all of the digits of the resulting numbers. For example, with the number given in step 1, doubling the digits, starting with the second-to-last one, yields 10 6 2 6 0 2 6 8. Adding all of the digits in these values yields 1 + 0 + 6 + 2 + 6 + 0 + 2 + 6 + 8 = 31. Add the sums of the two preceding steps. If the last digit of the result is zero (i.e., it is divisible by 10), the number is valid. In our case, 29 + 31 = 60, so the credit card number is valid.
