Leetcode Problem 2387. Median of a Row Wise Sorted Matrix

2387. Median of a Row Wise Sorted Matrix

Leetcode Solutions

Binary Search by Value

  1. Initialize left to the smallest element in the matrix and right to the largest element.
  2. Calculate the desired median position as (m * n) / 2 since the matrix has an odd number of elements.
  3. Perform a binary search: a. Calculate mid as the average of left and right. b. Count the number of elements in the matrix less than or equal to mid using a helper function that performs binary search on each row. c. If the count is less than or equal to the median position, set left to mid + 1; otherwise, set right to mid.
  4. When left meets right, the median value is found, and we return left.
