Reverse a Multi-digit Number

Problem Description

Given a natural number $a$ ($0 \le a \le 10^9$), print its digits in reverse order (leading zeros are allowed).

Input Format

One natural number $a$ ($0 \le a \le 10^9$).

Output Format

Print its digits reversed (leading zeros are allowed).

Sample Input

123500

Sample Output

005321

Constraints

$0 \le a \le 10^9$.

Hint

• Read the number, then peel off its digits one by one from the least significant end (modulo 10 and divide by 10), printing each digit as you go — this naturally produces leading zeros when the original ended in zeros.
• Alternatively, read it as a string and print it backwards.
