Send Feedback

Write a program to generate the reverse of a given number N. Print the corresponding reverse number.

Note : If a number has trailing zeros, then its reverse will not include them. For e.g., reverse of 10400 will be 401 instead of 00401.

Input format :

Integer N

Output format :

Corresponding reverse number

Constraints:

0 <= N < 10^8

Sample Input 1 :

1234

Sample Output 1 :

4321

Sample Input 2 :

1980

Sample Output 2 :

891
