C++ 4 Competitions

C++ for CP — templates, STL, bitwise, pointers.

c++ stl optional

What CP is, contests, and what to learn first.

Measuring Algorithms Performance

Big-O — learn this before heavy algorithms.

PHASE 02 Core topics

Number theory, primes, GCD, modular arithmetic.

primes gcd modular

Thinking Techniques

Brute force, divide & conquer, simulation.

brute force d&c

Data Structures

Stack, queue, PQ, trees, segment tree, BIT, DSU.

stack trees segment tree dsu

Search Techniques

Binary search, BFS, DFS and applications.

binary search bfs dfs

↓

PHASE 03 Advanced topics

String Processing

KMP, Z, hashing, trie, suffix structures.

kmp hashing trie

Dynamic Programming

Memoization, tabulation, knapsack, LCS, bitmask DP.

dp knapsack bitmask

Greedy Algorithms

Greedy choices and proof sketches.

Dijkstra, Bellman-Ford, MST, SCC, topo sort, flow.

PHASE 04 Practice & contests

Practice — Div2 A

Codeforces Div2 A — start after Phase 2.

codeforces div2-a

Practice — Div2 B

Codeforces Div2 B — after you are comfortable with A.

codeforces div2-b

Contest Strategies

Time management, problem order, mindset.

ℹ

Tips: Skip or skim C++ (02) if you already know C++. Math (05) and Thinking (06) can be parallel. Start Div2 A (13) right after Phase 2 — don’t wait until Phase 3 is finished. Do DP (10) before heavy Graph (12).
