Grokking the Coding Interview Patterns in C#

Solution: Maximal Rectangle

Explore the dynamic programming approach to identify the largest rectangle consisting only of ones in a binary matrix. This lesson helps you understand how to transform each row into a histogram and use arrays to track heights and boundaries, enabling efficient calculation of the maximal rectangle area. You'll gain skills to solve similar optimization problems in coding interviews.

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 ...
