Write pseudocode to solve the following problem:

You are given an array A[1...n] whose each element is a point of the plane (x,y). You need to sort the array so that points with lower x-coordinates come earlier, but among points with the same x-coordinate, the ones with larger y-coordinate come earlier.

So, for example, if the array contains:

(1,2), (1,4), (7,10), (11,3), (14,1), (7,2)

The output, in this case, should be:

(1,4), (1,2), (7,10), (7,2), (11,3), (14,1)

Analyze the running time of your algorithm as a function of n
