It picks an element as pivot and partitions the given array around the picked pivot. There are many different versions of quickSort that pick pivot in different ways. Always pick first element as pivot. Pick a random element as pivot. Pick median as pivot.1. You basically need to understand, how does a Comparator work.

When the sort () function compares two values, it sends the values to the compare function, and sorts the values according to the returned (negative, zero, positive) value. If the result is negative, a is sorted before b. If the result is positive, b is sorted before a. If the result is 0, no changes are done with the sort order of the two values. The problem is to sort the given matrix in strict order. Here strict order means that matrix is sorted in a way such that all elements in a row are sorted in increasing order and for row ‘i’, where 1 <= i <= n-1, first element of row 'i' is greater than or equal to the last element of row 'i-1'.
