Contiguous Array - Leetcode 525 - In Hindi

Описание: 📌 Leetcode 525 – Contiguous Array
In this video, we solve the Contiguous Array problem using an optimal approach with prefix sums and a hashmap in Python.

We aim to find the maximum length of a contiguous subarray with an equal number of 0s and 1s.

🧠 What You’ll Learn:
Transforming binary array problems into prefix sum problems

Using HashMap to track first occurrences of prefix values

Efficient O(n) time complexity approach

🔍 Time & Space Complexity:
Brute Force:
⏱️ O(n²) – Try every subarray and count 0s and 1s

Optimized (HashMap):
⏱️ O(n) time, O(n) space – Track running count and first occurrence
