Logic:

Does your code follow the condition

( i < j )

can you please elaborate above condition or provide any test case for which my code give wrong answer.

@pushpinder001 , I meant, that in the problem statement, it says " He needs to report the number of pairs (i,j) where i < j … " . So I’m asking if you are following that condition.

yes my code is following (i<j) condition.
