Data Structures and Algorithms are essential for anyone dealing with programming. They build a strong foundation and teach you fundamental skills. Most coding interviews require you to have a firm grasp in your algorithmic skills.\n\nAs we all know LeetCode started a wonderful 30-Day LeetCoding challenge for the past 3 months and I\u2019ve successfully solved all problems. This makes it a **90-Day Challenge**! Sometimes it was difficult as I\u2019d have exams or in general have things to do, but I made sure to _not_ skip a day, once even solving a problem _15-min_ before the day got over :D\n\nYou can find all my solutions on my GitHub repo: [Coding-Problems](https://github.com/Mohammed-Shoaib/Coding-Problems/tree/master/LeetCode)\n\nAll the best to everyone taking the July challenge! You can do this, believe in yourself.\n\n![image](https://assets.leetcode.com/users/images/2ba7f903-45f2-44cc-9bab-c964bb215e6e_1593763282.284044.png)\n\n**#30DayChallenge #LeetCode #DataStructures #Algorithms #CodingProblems**
