The judge is not accepting the solution.

I would like to bring this in notice that the Question: Sum Pairs. is not giving AC.(Even if you type old successful codes)
Please do check.

Did you try only submitting only 1 such solution or multiple? Can you please try multiple (3-5)? If they all are giving WA, then we will look into it :slight_smile:

Point is, its possible that test cases got updated to prevent weak solutions, which passed earlier, to pass now.
