WA in Funny Marbles

Here’s my solution : Link

Any test case where this is failing?

Declare all integers as long long :slight_smile: , this is the only mistake you are doing .

Edit:-

just declare your ‘tree’ array as long long , because you are returning the array element to long long find_sum

Isn’t it enough to take just their sum as long long?

But the sum may exceed right ???
