Grokking the Coding Interview Patterns in Go

Solution: Single Number

Understand how to apply bitwise XOR operations to find the element that appears only once in an array where all others appear twice. This lesson teaches you to implement an efficient algorithm that runs in linear time and uses constant space, helping you solve this common coding interview problem with a clear approach.

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
...
