Reverse Integer

Given a signed 32-bit integer \( n \), reverse its digits. If the reversed integer is out of the 32-bit signed integer range, i.e., if it is less than \( -2^{31} \) or greater than \( 2^{31}-1 \), return 0. Otherwise, return the reversed integer.

For example, if the input is 123, the output should be 321; if the input is -456, the output should be -654; and if reversing the integer causes an overflow, the output should be 0.

The input consists of a single integer \( n \), provided via standard input.

outputFormat

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