Reverse Integer

You are given a 32-bit signed integer n. Your task is to reverse its digits while preserving its sign. If the reversed integer overflows the 32-bit signed integer range \( [-2^{31}, 2^{31}-1] \), then output 0.

Example: If n = 123, then the reversed integer is 321.
If n = -456, then the reversed integer is -654.

The input will be read from standard input (stdin) and the result should be printed to standard output (stdout).

inputFormat

The input consists of a single integer \( n \) provided in one line from the standard input.

outputFormat

Output the reversed integer. If the reversed integer is outside the 32-bit signed integer range \( [-2^{31}, 2^{31}-1] \), output 0.

123

321
