Competitive programming starter notes for engineering students beginning on Codeforces, CodeChef, LeetCode and AtCoder. Explains how to read constraints and choose the right complexity, a C++ template with fast input and output, the STL containers and algorithms you will use most, common techniques such as prefix sums, two pointers, binary search on the answer, greedy, bit manipulation, modular arithmetic, sieve, graph traversal and basic dynamic programming, plus a practice roadmap and contest strategy for steady rating growth.
