Course Overview

This course contains unpublished lessons to be used in Paths.

What You'll Learn

Apply two-pointer and sliding-window techniques to optimize array and string problems to O(n)

Implement dynamic programming solutions using memoization or tabulation for counting and optimization tasks

Use modified binary search to solve rotated-array and median-partition problems in logarithmic time

Solve interval scheduling problems using sorting and heaps to detect overlaps and allocate resources

Traverse trees and BSTs to compute properties and queries (depth, balance, LCA, kth smallest, subtree)

Build and query graph solutions using BFS/DFS, Union-Find, and topological sort for connectivity and reachability

Design trie-based data structures to implement file system operations and lexicographical traversal

What You'll Learn

Apply two-pointer and sliding-window techniques to optimize array and string problems to O(n)
