Solution: Maximal Rectangle

Explore how to use dynamic programming to compute the largest rectangle containing only ones in a binary matrix. Understand how to transform each row into a histogram and use auxiliary arrays to track boundaries and heights for efficient area calculation. Gain the skills to solve this optimization problem with a linear time approach.

We'll cover the following...

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 ==== matrix[i].length

  • 1≤1 \leq rows, cols ≤200\leq 200 ...
