LeetCode 1269. Number of Ways to Stay in the Same Place After Some Steps(Hard) - JAVA

Title: "Dynamic Programming Explained: Solving a Pointer Problem" Description: In this tutorial, we dive into a fascinating dynamic programming problem involving a pointer and an array. We'll walk you through the problem statement, providing a clear understanding of the challenge at hand. Problem Statement: You are given an array of length arrLen, and a pointer initially at index 0. At each step, you can move either one position to the left, one position to the right, or stay in the same place. The goal is to find the number of ways you can take exactly steps steps while still ending up with the pointer at index 0. We'll guide you through the thought process, breaking down the problem into manageable parts. Solution Walkthrough: We'll explain the approach step by step, without showing the code, to ensure a solid understanding. We cover important concepts such as dynamic programming, modulo operations, and loop iteration. You'll grasp the logic behind each line of code, making it easy to implement the solution in your own projects. Key Takeaways: Understanding the problem statement Applying dynamic programming techniques Preventing integer overflow with modulo operations Iterating through steps and positions effectively By the end of this tutorial, you'll have a solid grasp of dynamic programming and be equipped to tackle similar challenges in your coding journey.
