Whiteboard Interview with Arrays and Hash Maps - Whiteboard Wednesday

Check out the detailed data structures and algorithms course at https://www.interviewaccelerator.com

Welcome to Whiteboard Wednesday where I do programming (software engineering) interview problems on the whiteboard in a real interview setting.
Problem: You are given an array of repeating numbers. All numbers repeat in an even way, except for one. Find that odd occurring number.

As we want to mimic a real interview, I don't see the problems ahead of time. I see them for the first time when I solve them here. This way, you can see my problem solving methods and how I interact with the interviewer. You also see me struggle sometimes, it's all part of the package :)
