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

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

This problem also can be solved using the same trick

@Riddhi EOF is == 1. While thinks it as TRUE. So, after getting the last number while loop won't stop. As a result scanf will try again to take a number but there is nothing left to take input in judge data. Thus you program will cause a RTE. Last edit: 20180420 07:28:54

didn't know that <while(scanf("%d", &n))> gives runtime error
