Leetcode Problem 2373. Largest Local Values in a Matrix

2373. Largest Local Values in a Matrix

Leetcode Solutions

Iterative Traversal with Nested Loops

  1. Initialize an empty (n - 2) x (n - 2) matrix called maxLocal to store the maximum values.
  2. Iterate over the rows of the grid from 0 to n - 3 (inclusive).
  3. For each row, iterate over the columns from 0 to n - 3 (inclusive).
  4. For each position (i, j), initialize a variable maxValue to store the maximum value found in the 3x3 submatrix.
  5. Iterate over the 3x3 submatrix centered at (i + 1, j + 1) and update maxValue with the maximum value found.
  6. Assign maxValue to maxLocal[i][j].
  7. Continue this process until all positions in maxLocal are filled.
  8. Return the maxLocal matrix.
