Hi!

Is there a data structure that can perform the following queries (in logaritmic time)?:

(a) for (i = 1; i <= n; i++) A[i] += B[i]

(b) given l and r perform for (i = l; i <= r; i++) B[i] = C

(c) given i, return the value of A[i]

Thanks!

Hi!

I was playing around with sorting algorithms and came up with this ideea

Also if you think that variations of this code (like changing the order in which we go through the powers of 2) could work better please let me know.

Thanks!
