In this article, we will explore the Two Pointer pattern in detail. We’ll discuss what it is, when to use it, and go through some classic examples to illustrate how powerful it can be. What is the Two Pointer Technique in Coding? The Two Pointer technique is a pattern where two pointers (or indices) are … Read more
Problem-solving patterns, also known as problem-solving techniques or strategies, are systematic approaches that can help you tackle coding and algorithmic challenges more effectively. Here are some problem-solving patterns commonly used in coding: (1). Two Pointers Use two pointers that traverse the data structure from different directions to solve problems efficiently. This is common in problems … Read more
