Grokking the Coding Interview Patterns in C#

Single Number

Explore how to identify the unique element in an array using bitwise manipulation in C#. This lesson helps you understand and implement an efficient solution with linear runtime and constant space complexity by analyzing problem constraints and applying XOR logic.

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 nums.length
...
