Question 1 Write function collatz, that takes a positive integer x as input and prints the Collatz sequence starting at x. A Collatz sequence is obtained by repeatedly applying this rule to the previous number x in the sequence: 3/2 if x is even 3.2 +1 if x is odd. Your function should stop when the sequence gets to number 1. Note: It is an open question whether the Collatz sequence of every positive integer always ends at 1. >>> collatz(10) 10

Answer 1

def collatz(n):
    # Looping till n becomes 1
    while(not n==1):
        # Checking if n is even
        if(n%2==0):
            # Making n to its half
            n=n//2
        # Checking if n is even
        else:
            # Changing value of n to 2n+1
            n=3*n+1
        # Printing value of n
        print(n)

# Testing
def main():
    # Reading input from user
    n = int(input("Please enter a positive integer: "))
    # Making call to collatz function
    collatz(n)
    
main()
