/*
* Given two integers, using bit manipulations determine if they are of opposite signs.
* Most Significant Bit (MSB) of number represents sign of the number. If it is 1, it represents
* a negative value, if it is 0, it represents a positive value.
* If MSB of two numbers are different, their XOR would be 1, otherwise it would be 0.
* Thus, result of XOR of two numbers will have MSB 1 if they are of opposite signs,
* 0 other wise, in other words, XOR of two numbers would be negative (MSB 1) if they are of
* opposite signs.
