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

Took a day to solve it. Not an easy one. My first in Segment Trees. |

@admin I think you must add JAVA in the list of unsupported languages as well |

@swas99 I managed to use Fast IO keeping the source limit<5000B but the time limit is too strict for java

@ kaushal101 always take the value in leaf node not max(0,A[L])

Finally solved it :) :) Feels good, use scanf , printf , cin and cout will not work even on using sync_with_stdio(false), will have to implement segment trees using pointers as array implementation would be complicated and memory consuming , finally don't give up, its a beautiful problem on segment trees will teach you a lot. |
