The following reusable segment tree implementation uses 0-based indexing with half-open intervals [l, r). It supports point assignment, point addition, range queries, and methods to locate the first or last endex satisfying a custom predicate. #include <bits/stdc++.h> template<typename Info> struct SegmentTree { int size = 0; ...

Construction AlgorithmThe Linear Basis structure maintains a set of linearly independent vectors to solve problems involving the XOR operation. To insert a value into the basis, we process the bits from the most significant bit (MSB) to the least significant bit (LSB).Let basis[] be the array storing the basis elements, initialized to 0. For an ...

Arrays in Go represent fixed-length sequences of elements with the same type. Each element in an array is accessible by its index, and the total number of elements defines the array's length. Array Declaration Syntax Go provides several ways to declare arrays: var byteArray [32]byte // 32-element byte array var pointArray [1000]*floa ...

HashSet implements the Set interface in Java using a hash table as its underlying data structure. It maintains a collection of unique elements, preventing duplicate entries from being stored. Each element in a HashSet is associated with a unique key derived from its hashCode() method. This hash value serves as an index for storing and retrievin ...
