my code worked…i have a doubt though
i am using 3d fenwick tree
for update when i was keeping my loop as i=a; i<(N+1); i+=(i&(-i)) it wasnt working…when i changed the N+1 to 105 (size of my fenwick tree) it worked…isnt it enough to check till N+1 always?? as fenwick tree goes from 1 to N??

Might be some implementation issue
As you may see even here https://www.hackerearth.com/practice/data-structures/advanced-data-structures/fenwick-binary-indexed-trees/practice-problems/algorithm/counting-in-byteland/editorial/
If you update till just N it is fine which you did as well
You can compare your approach with this once and see what the issue might be
