📖 Roadmap for Competitive Programming (Python + Codewars)

This file outlines my learning journey step by step.

Stage 1: Python Foundations

• Variables, loops, conditionals, functions
• Data types (strings, lists, sets, dicts)
• Input/Output practice
• Basic math (mod, gcd/lcm)

Stage 2: Problem-Solving Patterns

• Brute force vs optimized
• Two pointers
• Sliding window
• Prefix sums
• Hash maps & sets

Stage 3: Data Structures & Algorithms

• Sorting & searching
• Recursion & backtracking
• Stacks, queues, linked lists
• Trees and traversals

Stage 4: Number Theory

• Primes & sieve
• Modular arithmetic
• Combinatorics
• Bitwise tricks

Stage 5: Dynamic Programming

• 1D DP (Fibonacci, coin change)
• 2D DP (LCS, knapsack)
• Optimization techniques

Stage 6: Graphs

• BFS, DFS
• Shortest paths (Dijkstra, Bellman-Ford)
• MST (Kruskal, Prim)
• Topological sort

Stage 7: Advanced Topics

• String algorithms (KMP, Rabin-Karp)
• Segment trees, Fenwick trees
• Union-Find
• Geometry basics
• Advanced DP
