Solution: Maximal Rectangle

Explore how to solve the maximal rectangle problem in a binary matrix by applying dynamic programming techniques. Learn to convert each row into a histogram and use three arrays to track heights and boundaries, enabling efficient calculation of the largest rectangle area. This lesson builds skills in handling matrix-based DP problems with optimal time and space complexity.

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 ==== ...
