you don’t need to take unique elements from the array, it is causing error.
In this question you just need to take for pairs like for eg:- (2,2) where first 2 is from 1 and second 2 is also from index 1.
But (2,2) is accepted when first ‘2’ is from some index 1 and second ‘2’ is from index 2.

still after removing the unique line this is my modified code…https://ide.codingblocks.com/s/244242 still its showing wrong answer for all the testcases.

you need to correct some more things in your code:-

  1. You just don’t need to check if y is equal to your current element or not, what exactly you need to check is the pair (Ai, Aj) you are getting in that i != j, bcoz the value can be equal but the element should be different.
  2. Also the given array can contain duplicates, so for eg arr[] = 2,3,3,3,5 so here there can be three pairs of (2,3), so add all.

Don’t need to do much changes in the code, you can have a look at corrected code of yours if you need https://ide.codingblocks.com/s/244769
