1727. Largest Submatrix With Rearrangements

Leetcode Solutions

Sort By Height On Each Baseline Row

  1. Initialize m as the number of rows and n as the number of columns in the matrix.
  2. Initialize ans to 0 to keep track of the maximum area found.
  3. Iterate over each row row from 0 to m: a. If row is greater than 0, iterate over each column col from 0 to n: i. If matrix[row][col] is not 0, add matrix[row - 1][col] to matrix[row][col]. b. Copy matrix[row] to currRow and sort currRow in descending order. c. Iterate over currRow with index i: i. Calculate the area as currRow[i] * (i + 1). ii. Update ans with the maximum of ans and the calculated area.
  4. Return ans.
