This article demonstrates how to implement common sorting algorithms using C++ class templates with dynamic array storage. The implementation includes ranking sort, selection sort with early termination, bubble sort with early termination, and insertion sort. Requirements No STL containers (arrrays, vectors, etc.) Must use class templates (temp ...

C++ templates enable writing generic code that works with different data types without rewriting the entire code for each type. They are broadly categorized into function templates and class templates. Function Templates Function templates provide a mechanism to define a generic function that can operate on different data types. The compiler ge ...

Competitive programming demands a high degree of code reusability. Below is a curated set of templates that have been fine-tuned for typical on line judges, including a comprehensive header, fast input/output routines, a modular arithmetic wrapper, and implementations of the suffix automaton and suffix array. Compact Header with Utilities names ...

Core Syntax Structure The definition requires declaring type parameters before the class name. A typical implementation follows this pattern: template<typename KeyType, typename ValueType> class Entity { public: Entity(KeyType id, ValueType data) { this->identifier = id; this->metric = data; } void di ...
