After getting negative contribution to my pervious blog (Asking about will I go to specialist by 2023), I have raged up my problem solving limits and become Blue now...!
Topic to cover mostly :
1) Maths — Combinatorics, Modular arithmetics, Prime properties
2) Prefix & Suffix optimizations
3) Basic DP , Recursion , Graph , Tree implementations
4) Implementation skills — You have to ready to convert your thought process into code easily
5) STL usage is very important
6) Binary search
7) Bit manipulations
Tips :
1) Don't try the topics you have learned in recent days into all the problems
2) Think of the solution without thinking any algorithms — just use that algorithms if you need optimization or it is basic need in your approach
3) Spend quality of time in each and every problem you solve — I have spent a whole day for a 1700 problem in my practice session before ICPC regionals
4) Enhance your debugging skills
5) Don't give up and keep trying — a single push can lift you beyond your imaginary level — For me that push is ICPC regionals
