Solution: Maximal Rectangle

Explore the dynamic programming technique to solve the maximal rectangle problem in a binary matrix. Understand how to transform each row into a histogram and use height and boundary tracking arrays to efficiently compute the largest rectangle of 1s. This lesson equips you with a solid approach to optimize area calculations while managing time and space complexity for matrix processing.

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

  • 11 \leq rows, cols 200\leq 200 ...
