Algorithm to detect whether two numbers have opposite signs using bitwise operators

We present a bitwise algorithm to detect whether two numbers have opposite signs. This is important as using comparision based operations is slow and nearly all hardware support optimizations for bitwise operations

Bitwise Algorithm to Find the Number Occurring with Odd Frequency

We have explored the bitwise algorithm to find the only number occuring odd number of times in a given set of numbers. We have used the XOR operator to solve this problem in O(N) time complexity in contrast to the native algorithm which takes O(N^2) time complexity. The space complexity is constant.
