Write a program called hw2_1.cpp (or hw2_1.java) that reads a positive integer number from a user and displays the reverse of the number. For the program, you can assume that the input number is in the range of the typical int data type.

Sample Run 0: Assume that the user typed the following number.

1234321

This is the correct output.

1234321

Sample Run 1: Assume that the user typed the following number.

425

This is the correct output.

524

Sample Run 2: Assume that the user typed the following number.

1200

This is the correct output. Note that the reverse of 1200 is not 0021. It should be 21 because we should remove the leading zeros.

21
