Grokking the Coding Interview Patterns in Go

Solution: Single Number

Understand how to use the bitwise XOR operator to efficiently identify the single number in an array where every other element appears twice. Practice implementing a linear time and constant space solution using XOR properties for coding interviews.

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
...
