45. Jump Game II (Medium)

Posted on April 25, 2024April 25, 2024 By thecodepathshala 1 Comment on 45. Jump Game II (Medium)

You are given a 0-indexed array of integers nums of length n. You are initially positioned at nums[0]. Each element nums[i] represents the maximum length of a forward jump from index i. In other words, if you are at nums[i], you can jump to any nums[i + j] where: 0 <= j <= nums[i] and i + j < n Return the minimum number of jumps to reach nums[n -…

55. Jump Game (Medium)

Posted on April 25, 2024April 25, 2024 By thecodepathshala No Comments on 55. Jump Game (Medium)

You are given an integer array nums. You are initially positioned at the array’s first index, and each element in the array represents your maximum jump length at that position. Return true if you can reach the last index, or false otherwise. Example 1: Input: nums = [2,3,1,1,4] Output: true Explanation: Jump 1 step from index 0 to 1, then 3…

🔌 Adapter Design Pattern Explained | Real-Life Analogy + Code Examples

Ever wanted two incompatible interfaces to work together? That’s exactly what the Adapter Pattern is for!

In this video, you’ll learn how the Adapter Design Pattern helps you connect mismatched interfaces using real-world analogies (like charging adapters!) and clear code demos.

🎯 What You’ll Learn:
✅ What is the Adapter Pattern?
✅ Real-life analogies that make it easy to remember
✅ How to implement it in code (Class Adapter vs Object Adapter)
✅ When to use it and common pitfalls to avoid

💡 Part of the Structural Design Patterns, the Adapter is perfect when:

You want to integrate legacy code with modern systems

You need to work with incompatible APIs

You're preparing for coding interviews or system design questions

👨‍💻 Great for:

Software Developers

Interview Prep (especially for FAANG roles)

Students learning OOP & Design Patterns
