Image Overlap | Leetcode 835 | Easiest Explanation | Java Solution | Calculating Range

In this video, I solve LeetCode 835 – Image Overlap using Java and explain the approach step by step. The problem is based on two binary matrices where we need to shift one image over the other and find the maximum number of overlapping 1s. 💡 What you'll learn: How to shift a 2D matrix using dx and dy How to handle matrix boundaries How to count overlapping 1s How to find the maximum overlap Step-by-step Java implementation Time and space complexity 📌 Approach: We try every possible horizontal and vertical shift of img1. For each shift, we check which 1s overlap with 1s in img2, keep track of the current overlap, and update the maximum result. ⏱️ Complexity: Time: O(N⁴) Space: O(1) If you're preparing for coding interviews, DSA, or LeetCode, this is a great problem to understand 2D arrays, matrix traversal, and coordinate shifting. 👉 Watch the full video to understand the problem and Java solution step by step. 🔔 Subscribe to Code Without Complexity for more LeetCode solutions and easy-to-understand DSA explanations. #LeetCode #Java #DSA #CodingInterview #Programming #LeetCode835 #ImageOverlap #JavaProgramming #Coding #SoftwareDeveloper #leetcodepotd #leetcode #leetcodepotd #strings #java #leetcodetodaysproblem #Leetcode835 #Leetcode today problem #leetcode problem today #leetcode 835 java #leetcode Image Overlap Java #Image Overlap Java #Image Overlap 835 Java #Java #LeetCode #LeetCode #leetcode83code without complexity #LeetCodeDailyChallenge #LeetCodeSolutions #LeetCodeString #LeetCodeeasy #LeetCodeJava #LeetCodeProblem #CodeWithoutComplexity #CodingMadeSimple #Coding #CodeNewbie #ProblemSolving #100DaysOfCode #TechWithCode #ProgrammerLife #Java #JavaProgramming #CodingInJava #DSAinJava#coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram #facebook #leetcode #computerscience #leetcodesolutions #leetcodequestionandanswers #code #learning #dsalgo #dsa #coding #programming #100daysofcode #developers #techjobs #datastructures #algorithms #webdevelopment #softwareengineering #computerscience #pythoncoding #codinglife #coderlife #javascript #datascience #leetcode #leetcodesolutions #leetcodedailychallenge #codinginterview #interviewprep #technicalinterview #interviewtips #interviewquestions #codingchallenges #interviewready
