GSS4  Can you answer these queries IV
You are given a sequence A of N(N <= 100,000) positive integers. There sum will be less than 10^{18}. On this sequence you have to apply M (M <= 100,000) operations:
(A) For given x,y, for each elements between the xth and the yth ones (inclusively, counting from 1), modify it to its positive square root (rounded down to the nearest integer).
(B) For given x,y, query the sum of all the elements between the xth and the yth ones (inclusively, counting from 1) in the sequence.
Input
Multiple test cases, please proceed them one by one. Input terminates by EOF.
For each test case:
The first line contains an integer N. The following line contains N integers, representing the sequence A_{1}..A_{N}.
The third line contains an integer M. The next M lines contain the operations in the form "i x y".i=0 denotes the modify operation, i=1 denotes the query operation.
Output
For each test case:
Output the case number (counting from 1) in the first line of output. Then for each query, print an integer as the problem required.
Print an blank line after each test case.
See the sample output for more details.
Example
Input: 5 1 2 3 4 5 5 1 2 4 0 2 4 1 2 4 0 4 5 1 1 5 4 10 10 10 10 3 1 1 4 0 2 3 1 1 4 Output: Case #1: 9 4 6 Case #2: 40 26

This is my first problem where using cin/cout with fast i/o didn't work. Whereas, scanfprintf got my job done!

Note that Ai may hold a negative number, this was not mentioned in the statement

Purely for optimization, sacrificed code quality for AC

Don't forget edge cases, when a query(l, r) has l > r;
