Here are some solutions about common problems that you might get by applying to technical interviews. You can find the solutions that I developed for these problems. Feel free to share a better solution in the comments. Most of the code problems I solved were taken from https://www.dailycodingproblem.com/ by subscribing to the page and https://www.udemy.com/11-essential-coding-interview-questions/.
