🔥 LeetCode 3714 | Longest Balanced Substring II (13-02-2026) | Easy Explanation

Описание: In this video, we solve LeetCode Problem 3714 – Longest Balanced Substring II step by step using an optimized approach.

You are given a string, and your task is to find the length of the longest balanced substring that satisfies the required conditions. Compared to Part I, this version introduces additional complexity, making it important to handle the balance efficiently.

🧠 Main Idea

The goal is to:

Traverse the string efficiently

Keep track of valid balance conditions

Identify the longest substring that satisfies the rule

Avoid checking all substrings (brute force)

By maintaining the required counts while scanning the string, we can detect balanced segments and update the maximum length.

⚙️ Approach Overview

To solve this problem efficiently, we may use:

Sliding Window Technique

Prefix Counting

Two Pointer Approach

Efficient String Traversal

This helps achieve an optimized O(n) solution.

📌 Key Concepts Covered

String Manipulation

Sliding Window

Pattern Recognition

Optimization Techniques
