CSES Problem Set Solutions

This repository contains my CSES problem set solutions in C++.

Each folder corresponds to a CSES category, and each file contains a fully working, commented solution.

Structure

• Introductory Problems — Basic logic, loops, and implementation.
• Sorting and Searching — Greedy, binary search, and prefix sums.
• Dynamic Programming — Classic DP transitions and state definitions.
• Graph Algorithms — BFS, DFS, Dijkstra, etc.
• Range Queries — Fenwick tree, segment tree.
• Tree Algorithms — DFS on trees, LCA, subtree sums. --Done

My Goal

To complete the entire CSES problem set, focusing on:

• Writing clean and efficient C++ code
• Understanding state transitions deeply
• Optimizing memory and runtime for each problem

Language

All solutions are written in:

• C++ 17
