Leetcode 2348. Number of Zero-Filled Subarrays | Counting Subarrays with Math | Python Solution

In this video,
We solve Leetcode 2348. Number of Zero-Filled Subarrays using a mathematical counting approach.
The idea is simple: every time we encounter consecutive zeros, we count all possible subarrays ending at that position. This avoids brute force and gives us an O(n) linear time solution.

🔥 Topics covered in this video:
Problem explanation with examples
How to count subarrays efficiently
Why consecutive zero streaks matter
Time complexity: O(n)
Space complexity: O(1)

Step-by-step Python solution
This problem is a great example of counting subarrays using patterns, and is very useful for interview preparation and strengthening your array problem-solving skills.

If you are preparing for coding interviews or practicing Leetcode problems (easy/medium), this is a must-solve!
