Fenwick Tree (Binary Indexed Tree)
Fenwick Tree’s efficiency, combined with its relatively simple implementation, makes it useful in competitive programming and applications that involve dynamic sum queries and updates.
Estimating Percolation in a Matrix Network
Dynamic connectivity algorithms provide an efficient way to model and analyze percolation in a grid of sites.
Comparing Performance of Disjoint-Set Algorithms: Quick Union, Quick Find, and Weighted Quick Union
Disjoint-set data structures, commonly known as Union-Find, are fundamental data-structures in computer science for efficiently solving problems related to connectivity in graphs or set operations.
