For this Question: Given an array of n pairs of integers. Your task is to sort the array on the basis of the first element of pairs in descending order. If the first element is equal in two or more pairs then give preference to the pair that has a greater second element value.<b>User Task:</b>
Since this will be a functional problem, you don't have to take input. You just have to complete the function <b>SortPair()</b> that takes the array of pairs and the integer N(size of the array) as a parameter.

<b>Custom Input <b/>
The first line of input will be a single integer N. The next line of input contains 2*N space-separated integers where unique adjacent elements are pairs. Custom input for 1st sample:-
4
1 2 3 4 5 6 7 8

<b>Constraints:-</b>
1<=N<=10<sup>3</sup>
1<=value<=10<sup>5</sup>Return the sorted array of pairs.Sample Input 1:
4
(1, 2), (3, 4), (5, 6), (7, 8)

Sample Output 1:
(7, 8), (5, 6), (3, 4), (1, 2)

Sample Input 2:
3
(1, 1), (2, 2), (3, 3)

Sample Output 2:
(3, 3), (2, 2), (1, 1)

Sample Input 3:
3
(1, 1), (1, 2), (3, 3)

Sample Output 3:
(3, 3), (1, 2), (1, 1)

<b>Explanation :</b>
(1,2) and (1,1) have the same first element. But (1,2) has a greater second element so (1,2) comes before (1,1) in a sorted array.
, I have written this Solution Code: 
      static Pair[] SortPair(Pair arr[], int n) 
    { 
        // Comparator to sort the pair according to second element 
        Arrays.sort(arr, new Comparator<Pair>() { 
            @Override public int compare(Pair p1, Pair p2) 
            { 
                if(p1.x==p2.x){
                    return p2.y-p1.y;
                }
                return p2.x-p1.x;
            } 
        });
        
        return arr;
  
  
    } 
, In this Programming Language: Java, Now tell me if this Code is compilable or not?
