Solution: Maximal Rectangle

Understand how to apply dynamic programming to compute the maximal rectangle of 1's in a binary matrix efficiently. This lesson guides you through transforming rows into histograms, using height, left, and right boundary arrays to identify the largest rectangle area. You'll learn to optimize your approach with an O(m×n) time complexity method suited for coding interviews.

Statement

Given a binary matrix filled with 0’s and 1’s, find the largest rectangle containing only 1’s and return its area.

Constraints:

  • rows ==== matrix.length

  • cols ==== ...
