1. Given a number, say, n. If it is divisible by 10, print the

   quotient when divided by 10, otherwise if it is divisible by 5,

   print the corresponding quotient, otherwise, print the number.

   Answer::

        if n%10==0:

            print n/10

        elif n%5==0:

            print n/5

        else:

            print n

2. Given a number, say, n. Write an if block to multiply n by three

   and add 1, if it is odd, otherwise halve it. 

   Answer::

        if n % 2:

            n = n*3+1

        else:

            n /= 2
