/**
 * This class provides a method to determine whether two integers have
 * different signs. It utilizes the XOR operation on the two numbers:
 *
 * - If two numbers have different signs, their most significant bits
 * (sign bits) will differ, resulting in a negative XOR result.
 * - If two numbers have the same sign, the XOR result will be non-negative.
 *
 * Time Complexity: O(1) - Constant time operation.
 * Space Complexity: O(1) - No extra space used.
