digit-reverse – Reverse decimal digits

Write a program that reads several integers, reverses their digits and prints the result. For example:

Input and Output

Input will consist of several lines each with a number d where 0 ≤ d ≤ 1 000 000 000. You should ignore leading zeroes on d if they are present.

For each line of input, output should contain a single line with a number b with the reversed digits of d. Do not print leading zeroes on b.

Input is terminated by the end-of-file (EOF).

Example input

6
720
1234
98765

Example output

6
27
4321
56789
