Leetcode 1358 | Number of Substrings Containing All Three Characters |Detailed Explanation | Dry Run

🚀 Leetcode 1358 - Number of Substrings Containing All Three Characters | Medium 📌 Problem: https://leetcode.com/problems/number-... 💻 Source Code: https://github.com/vijaykumar0710/lee... 🚀 Subscribe to my channel:    / @vijay_kumar_710   Timeline:- 00:00 Problem Explanation + Brute Force 13:09 Brute Force Code 15:47 Better Approach 26:10 Better Approach Code 27:10 Optimal Approach 37:40 Optimal Code In this video, we solve Leetcode 1358 step by step using Sliding Window and unordered_map. 📌 What You'll Learn: ✅ Problem Understanding ✅ Brute Force Approach ✅ Better Approach ✅ Optimal Sliding Window Approach ✅ How unordered_map helps track character frequency ✅ Dry Run ✅ Live Coding in C++ ✅ Time & Space Complexity Analysis 💡 This is a great beginner-friendly Sliding Window problem. We maintain a window that contains all three characters `a`, `b`, and `c`, then count valid substrings efficiently. 📚 Concepts Covered: • Sliding Window • unordered_map • String Processing • Frequency Counting • Two Pointers • Substring Counting ⏱ Complexity: • Time Complexity: O(n) • Space Complexity: O(1) 💻 Language Used: C++ #leetcode #leetcode1358 #slidingwindow #unorderedmap #strings #cpp #datastructures #algorithms #codinginterview#hashmap #cpp #datastructures #algorithms #competitiveprogramming #codinginterview #dsa#hashmap #subarrays #cpp #competitiveprogramming #datastructures #algorithms #codinginterview#leetcode #leetcode3737 #hashmap #arrays #subarrays #cpp #datastructures #algorithms #competitiveprogramming #codinginterview#cpp #competitiveprogramming #datastructures #algorithms #codinginterview#dynamicprogramming #dp #memoization #recursion #cpp #competitiveprogramming #datastructures #algorithms #codinginterview#hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge#leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #codeistory #codestor #codestory#codestory #code #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram
