Solution: Maximal Rectangle

Explore how to solve the maximal rectangle problem in a binary matrix using dynamic programming. Understand how to convert rows into histograms, track boundaries for rectangles, and compute the largest possible rectangle area efficiently. This lesson helps you apply these techniques with O(m*n) time complexity and O(n) space, enhancing your problem-solving skills with DP in C++.

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 ==== ...
