Problem
The median of a matrix is defined as the median of the median of all rows. Find the median of the matrix.
Explanation
To find the median, we need the numbers to be sorted in increasing order. To sort the numbers, we can use merge sort or inbuilt sort algorithm available in the languages. Once, we find the median of all rows, we can do the same trick to find the median of all rows.
