Not getting how to take query q and take sum q no of times

#1

please find the error and explain the solution
link to the code i wrote

#2

@rsumitaj problem is at line 18, where in j’s for-loop you have mis-typed ‘i’ at some places.

Also, one more modification for finding the answers of query you can do is, when you have find answer like (i,j) to (ei, ej) then if i==0 or j==0 or (i==0 && j==0).
In these cases you have to take care for -ve index while calculating the answer of query.

#3

can you please modify my codeon ide for the negative index

#4
