Algorithms

These are the list of Algorithms I have implemented with sufficient documentation in comments. Most of the implementations are based on sources available online (references mentioned in the comments).

Almost all implementations are ready-to-use for competitive programming contests.

List of algorithms:

1. Range Minimum Query :

• <O(NlogN), O(1)>
• <O(N), O(sqrt(N))>

2. Least Common Ancestor :

• <O(N), O(sqrt(N))>
• <O(NlogN), O(logN)>

3. Fenwick Tree :

• 1-D : logN - update, read
• 2-D : logN.logM - update, read
