Getting started with Competitive Coding

Tips from from an expert competitive programmer (Anudeep Nekkanti) for someone beginning competitive coding:

If I aim to start programming now, I would do it this way:

1. Solve 200 most solved problems on SPOJ, Problem by problem. In 2 months. (This will teach all standard problems, algorithms and implementation skills)
2. Solve problems from CodeChef and CodeForces for 2 months. (This will teach variations, we can read others solutions and learn better ways. Skip easy problems)
3. Solve problems from TopCoder for 2 months. (This will teach Dynamic Programming. Div 1 500p)
