GSS1 - Can you answer these queries I
You are given a sequence A[1], A[2] ... A[N] . ( |A[i]| ≤ 15007 , 1 ≤ N ≤ 50000 ). A query is defined as follows:
Query(x, y) = Max { a[i] + a[i+1] + ... + a[j] ; x ≤ i ≤ j ≤ y }.
Given M queries, your program must output the results of these queries.
Input
- The first line of the input file contains the integer N.
- In the second line, N numbers follow.
- The third line contains the integer M.
- M lines follow, where line i contains 2 numbers xi and yi.
Output
Your program should output the results of the M queries, one query per line.
Example
Input: 3 -1 2 3 1 1 2 Output: 2

@noob_2798 we have to find the maximum subsequence so it is necessary for them to be contiguous.

For the newbies you can see explanation on my blog(read the comments for explanation), copy the code on your IDE & remove unnecessary comments it will become short- <snip> Last edit: 2022-08-17 17:30:35 |
