Solution: Single Number

Explore the bitwise XOR technique to efficiently identify the single number in an array where all other elements appear twice. This lesson helps you understand how XOR properties eliminate duplicates in one pass, achieving linear runtime and constant space usage.

We'll cover the following...

Statement

Given an array of integers, where every element appears twice except for one, find the element that occurs only once.

Note: The solution must have linear runtime and constant space complexity.

Constraints:

  • 1≤1 \leq
