4. [10] Write a program that reads two integers separated by an operator such as +, -, x, /, and % (there are spaces between the operator and the operands), and outputs the result of the operation. For example :

   If the inputs are	The output should be
   The operation	The result
   23 + 12	35
   12 x 6	72
   142 / 12	11
   146 % 11	3
   23 - 12	11

5. [10] Write a program that converts times from 24 hour notation to 12 hour notation. For example, it should convert 14:25 to 2:25 PM. For example :

   If the inputs are	The output should be
   Time in 24 hour notation	Time in 12 hour notation
   9:25	9:25 AM
   12:25	12:25 PM
   14:23	2:23 PM
   14:63	Wrong Time !!!
   24:23	Wrong Time !!!

   Hints:

   • You should read the input time as a string, i.e., there are no spaces between the hour, the colon and the minutes.
   • The numeric value of a digit character is int(digit) - int('0')
