GSS3  Can you answer these queries III
You are given a sequence A of N (N <= 50000) integers between 10000 and 10000. On this sequence you have to apply M (M <= 50000) operations:
modify the ith element in the sequence or for given x y print max{Ai + Ai+1 + .. + Aj  x<=i<=j<=y }.
Input
The first line of input 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 following form:
0 x y: modify Ax into y (y<=10000).
1 x y: print max{Ai + Ai+1 + .. + Aj  x<=i<=j<=y }.
Output
For each query, print an integer as the problem required.
Example
Input: 4 1 2 3 4 4 1 1 3 0 3 3 1 2 4 1 3 3 Output: 6 4 3

This is complete nonsense. Why is the source limit so low? The standard is 50000 Bytes.

For Java, I had to use a faster scanner (using BufferedInputReader), as well as using StringBuilder for the output. Was able to finally get it to pass, though!

Can anyone please explain why the test case for 1 2 4 is equal to 4 and not 3? Is this an incorrect test case?

what does "wrong answer #0" mean?

I think in this problem using segment tree is so useful

how query: 1 2 4 giving output=4 shouldn't it be 3 (2+(3)+4)

Please increase the source limit. Some languages are more verbose than others and it's ridiculous that I have to give all my variables a 1character name just to fit a neatlooking implementation into 5k.
