Advent of Code 2021

• Hello everyone! This repository is about my solutions and experience with Advent Of Code, 2021.

• Their about page does a better job at explaining what it is.

• I believe that it is a really good way of brushing up your problem solving skills, especially if you are a preparing for technical interviews or just love problem solvng in general.

  I will be updating this README everyday with my experience/comments about the problems and concepts as well as keep the repository updated with the solutions for each with a delay of 1-2 days so that everyone gets a chance to attempt the problems on their own.

  Day	Experience	Resources
  01	First day. Starting off with some pretty easy problems. Bringing in the sliding window concept in part two.	GeeksForGeeks - Sliding Window Technique
  02	Second day having pretty easy problems too. Simple implementation - thats it. Nothing special.	-
  03	Sigh. So, I lost my enthusiasm and hence the long break. But I completed part 1 on time but finished part 2 quite late. I will try my best to catch up with the backlog. Used ArrayList and, particularly the removeIf methon to filter the elements.	GeeksForGeeks - ArrayList removeIf() method in Java
