Solution: Single Number

Understand how to use bitwise XOR to find the single unique number in an array where all other elements appear twice. This lesson guides you through a linear time, constant space complexity solution using bitwise manipulation.

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
...
