Collection of algorithms and data structures in Java, C++, Python, JavaScript, Scala, Haskell, Ruby

The following topics are covered:

• Trees: segment tree, Fenwick tree, k-d tree, R-tree, metric tree, quadtree, persistent tree, link/cut tree, binary heap, disjoint-sets, treap
• Graph algorithms: shortest paths, maximum flow, maximum matching, spanning tree, connectivity, biconnectivity, LCA
• String algorithms: suffix tree, suffix automata, suffix array, trie, Aho-Corasick algorithm, Knuth-Morris-Pratt algorithm, Z-function, hashing, parsing
• Sorting algorithms: quick-, merge-, heap-, bubble-, selection-, insertion-, counting-, radix-sorting; Kth order statistic
• Geometry algorithms: segments/lines/circles intersection, point in polygon query, convex hull, closest/furthest pair of points
• Combinatorics: permutations, combinations, arrangements, partitions
• Other: big numbers multiplication via fast Fourier transform, simplex algorithm
