Reverse a String

Given a single word S containing no spaces, print the word with its characters in reverse order.

For example, hello becomes olleh. A one-character word stays the same, and so does a palindrome like racecar.

Digits and mixed case are allowed and are simply reversed along with everything else.

Input

A single line containing the string S (no spaces).

Output

The characters of S in reverse order.

Constraints

1 <= length of S <= 100

Example 1

Input

hello

Output

olleh

Reading h-e-l-l-o backwards gives o-l-l-e-h.

Submit runs your code against 5 test cases — the 1 shown above plus 4 hidden ones covering the awkward cases. Run sample just tries the first example, which is usually what you want while you are still working it out.
