Sort Array by Frequency | Custom Comparator in Java 🔥 | Code With Rahul Kumawat | DSA

📌 Problem: We are given an array Arr[N] such that 0 ≤ Arr[i] ≤ 100. Sort the array based on: 1. Smaller frequency comes first 2. If frequency is same → smaller value comes first 3. If value is same → smaller index comes first 🚀 In this video you will learn: ✔️ How to count frequency efficiently ✔️ How to use Comparator in Java ✔️ Multi-level sorting logic ✔️ Interview level problem solving approach 💻 Tech Used: Java | C++ | DSA | Sorting | HashMap | Comparator 🔥 This question is very important for coding interviews & competitive programming. 📌 Playlist: DSA in Java 📌 Lecture: Sorting Concepts 👍 Like, Share & Subscribe for more DSA content! #DSA #Java #Sorting #CodingInterview #RahulKumawat
