Leetcode Submissions

Link to REPO.
Here, you’ll find problems solved using a variety of data structures, algorithms, and approaches.
Most problems were coded in Java.
Through solving these problems, I have reinforced the knowledge I’ve gained from class, become better able to identify which problem-solving strategy to use, and how to implement it quickly. My favorite techniques are two pointers (binary search included) and backtracking for how versatile they are. I also enjoyed solving problems using tries (for efficient searching) and two priority queues (for optimization subject to a constraint) as there’s something beautiful about their complex elegance.
