Adapting BIT to offline type problems
Difference between en1 and en2, changed 79 character(s)
**Consider the following problem
==================
:**

Given an initial array of 
"n"$n$ integers and "q"$q$ queries of the form:↵

I x V$I$  $x$ $V$ : Add V$V$ to the i$i$-th position on the vector. If it is not empty (equals 0) then add it between the position xs $x$ and $x + 1$.↵

S x y$S$ $x$ $y$ : Calculate the sum of all elements from index $x$ to y$y$, inclusively.↵

My teacher has advised 
to tryus to use *RMQ* or an o*Offline Segment Tree* for this one, but i would like to know if there´s a way of adapting the Fenwick Tree to support this sort of "*shift"* that may need to be done on the vector efficiently.
