Grokking the Coding Interview Patterns

Single Number

Explore how to solve the problem of finding the element that appears only once in an array where all others appear twice. Learn to apply bitwise manipulation techniques to achieve a solution with linear runtime and constant space, enhancing your problem-solving skills 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 nums.length ≤
