Largest Local Values In A Matrix: Finding 3x3 Max Values
Generate an integer matrix maxLocal of size (n - 2) x (n - 2) where maxLocal[i][j] is largest value in every contiguous 3x3 matrix in grid.
2373. Largest Local Values in a Matrix Easy You are given an n x n integer matrix grid. Generate an integer matrix maxLocal of size (n - 2) x (n - 2) such that: maxLocal[i][j] is equal to the largest value of the 3 x 3 matrix in grid centered around row i + 1 and column j + 1. In other words, we want to find the largest value in every contiguous 3 x 3 matrix in grid. Return the generated matrix. Example 1: Input: grid = [[9,9,8,1],[5,6,2,6],[8,2,6,4],[6,2,2,2]] Output: [[9,9],[8,6]] Explanation: The diagram above shows the original matrix and the generated matrix.\ Notice that each value i...
