Bitwise MCQ: Which Operator Finds the Odd Occurring Number? | XOR Logic in C

Описание: In this MCQ, we explore one of the most common and powerful bitwise tricks used in C programming and competitive coding: finding the number that appears an odd number of times.

The logic relies on a unique property of one bitwise operator that cancels out matching pairs of numbers and leaves only the odd-occurring element.

This question is extremely popular in:
C programming interviews
Data structures & algorithms
Bit manipulation problems
Competitive programming

Correct answer: XOR (^)
