# 2387. Median of a Row Wise Sorted Matrix

## Description

Given an m x n matrix grid containing an odd number of integers where each row is sorted in non-decreasing order, return the median of the matrix.

You must solve the problem in less than O(m * n) time complexity.

Example 1:

Input: grid = [[1,1,2],[2,3,3],[1,3,4]]
Output: 2
Explanation: The elements of the matrix in sorted order are 1,1,1,2,2,3,3,3,4. The median is 2.


Example 2:

Input: grid = [[1,1,3,3,4]]
Output: 3
Explanation: The elements of the matrix in sorted order are 1,1,3,3,4. The median is 3.


Constraints:

• m == grid.length
• n == grid[i].length
• 1 <= m, n <= 500
• m and n are both odd.
• 1 <= grid[i][j] <= 106
• grid[i] is sorted in non-decreasing order.
