For this Question: Given an unsorted integer array having distinct integers, find a pair with the given sum in it.
First element of pair > second element of pairFirst line of input contains a single integer N, next line contains N space separated integers depicting the values of array and third line consist target sum.

Constraints:
2<=N<=5*(10^5)
1<=A[i], target<=2*(10^9)
TargetPrint the pair of integers which sum is target.
Sample Input1:-
6
8 7 4 5 3 1
10

Sample Output:-
Pair found (7, 3)


Sample Input2:
 6
5 2 6 8 1 9
12
 
Sample Output:
Pair not found, I have written this Solution Code: import java.io.*;

class Main{
    public static void swap(int[] arr,int i, int j){
        int temp=arr[i];
        arr[i]=arr[j];
        arr[j]=temp;
    }
    public static int partition(int[] arr,int l,int r){
        int pivot=arr[r];

            if(arr[j]>pivot){
                i++;
                swap(arr,i,j);
            }
        }
        swap(arr,i+1,r);
        return i+1;
    }

        if(l<r){
            int pivot=partition(arr,l,r);
            quickSort(arr,l,pivot-1);
            quickSort(arr,pivot+1,r);
        }
    }
    public static void main (String[] args) {

        Scanner sc=new Scanner(System.in);
        int n=sc.nextInt();
        int arr[]=new int[n];
        for(int i=0;i<n;i++){
            arr[i]=sc.nextInt();
        }
        int target=sc.nextInt();
        quickSort(arr,0,n-1);
        int i=0,j=n-1;
        while(i<j){
            if((arr[i]+arr[j])==target){
                System.out.print("Pair found ("+arr[i]+", "+arr[j]+")");
                return;
            }
            else if((arr[i]+arr[j])<target){
                j--;
            }
            else{
                i++;
            }
        }
        System.out.print("Pair not found");
    }
}, In this Programming Language: Java, Now tell me if this Code is compilable or not?
