Competitive programming resources

Here are some resources which I refer to for CP, feel free to add anything important

→ Place to find everything related to CP books, blogs, tutorials, platforms and everything you will ever need

→ How to decide which type of algorithm will be best for the question depending on the input size (very helpful if you are just starting out)
Overcoming TLE

→ For python coders

→ Simplified time complexity analysis

→ Implementation of any algorithm you will ever come across

→ Another resource for all programming algorithms


Few more resources of all curious folks out there
