/*help me to identify my error (giving wrong ans)*/

pls allign the code properly, its quite tough to understand. best will be if you can give a link of your submission

moreover , regarding the question .

- first sort the array.
- store presums in array
- start rolling over from 1-arr[n-1].
- use the presums + the number*(no greater then them) to check.

regarding your solution , i find you are doing it in O(n*n).do it in O(nlogn).

here is a link to my code.

do upvote if u understand , else ask .
