Matrix Median Calculation

Given an m x n matrix of integers, find the median of the matrix efficiently. The median is defined as the middle element when the elements are sorted. If the number of elements is even, it is the average of the two middle elements. Input Format: - The first line contains two integers, m and n, representing the dimensions of the matrix. - The next m lines contain n integers each. Output Format: - A single floating point number representing the median of the matrix, rounded to 6 decimal places. Example: Input: 3 3 1 3 3 3 5 6 1 2 4 Output: 3.0
