# Exercise  - Calculator
# 45 * 3 = 555, 56+9 = 77, 56/6 = 4
# Design a calculator which will correctly solve all the problems except
# the following ones:
# 45 * 3 = 555, 56+9 = 77, 56/6 = 4
# Your program should take operator  and the two numbers as input from the user
# and then return the result
