1.First sort the given array.
2.Now take two variables one as left and other as right starting from 0th and end index of the sorted array respectively.
3.Now iterate till left<right.
3.1 Calculate the sum of the elements at left and right position
3.1.1 If the sum is equal to the target then print both the elements. //printing target sum pairs
3.1.2 If the sum is less than the target then increase the left by 1
3.1.3 Else decrease the right by 1
4.End loop.Thus, all the pairs has been printed .

#4 
public static void roses(int[] arr, int target) {

     Arrays.sort(arr); // sort the Array

     int fl = 0;  //To store the leftmost index
     int fr = 0;    //To store the rightmost index

     int left = 0;
     int right = arr.length - 1;

     while (left < right) {

          int sum = arr[left] + arr[right];

          if (sum > target) {
               right--;
          } else if (sum < target) {
               left++;
          } else {
               fl = left;
               fr = right;

               left++;
               right--;
          }

     }

     System.out.println("Deepak should buy roses whose prices are " + fl + " and " + fr + ".");
