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 1018. On this sequence you have to apply M (M <= 100,000) operations:
(A) For given x, y, for each elements between the x-th and the y-th 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 x-th and the y-th 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 A1.. AN.
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

for queries and updates take care of if x>y: swap(x,y) |

use ios_base::sync_with_stdio(false); cin.tie(NULL); in your code if you are using cin and cout. Faster than scanf and printf in my case. |

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

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