Data Structure that is able to perform this queries

Revision en2, by BlueDiamond, 2020-05-13 17:18:10

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!
