For example, suppose we wish to sort a hand of cards such that the suits are in the order clubs (♣), diamonds (♦), hearts (♥), spades (♠), and within each suit, the cards are sorted by rank. Sep 15, 2025 · The Two-Pointers Technique is a simple yet powerful strategy where you use two indices (pointers) that traverse a data structure—such as an array, list, or string—either toward each other or in the same direction to solve problems more efficiently. Sep 6, 2023 · Two Pointer Technique Two Pointer Technique is a useful strategy for solving a variety of array-based problems in a more efficient manner. Jul 8, 2025 · The two-pointer technique is one of the most elegant and efficient algorithmic patterns in computer science. By using two pointers to traverse data structures (typically arrays or strings), we can 2 days ago · A Sorting Algorithm is used to rearrange a given array or list of elements in an order. Given a sorted array A (sorted in ascending order), having N integers, find if there exists any pair of elements (A [i], A [j]) such that their sum is equal to X. . Sorting algorithm specifies the way to arrange data in a particular order. Sorting algorithms are a fundamental part of computer science and are essential for efficient data manipulation and analysis. Mar 17, 2025 · The Two Pointers Technique is a straightforward but effective algorithmic technique that uses two pointers to traverse an array or linked list at the same time.
