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 i-th 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

"Wrong Answer #0", Anyone can tell me, why i am getting like this, while my code works perfect for GSS1(AC) and i have checked my point update previously(it is also correct).
and changed min value to -1000000.
But getting WA.

Ac in one go :p
GSS1 with addition of update function.

"Wrong Answer #0" How?
After AC:
I used LONG_MIN as default min value.

A nice problem to solve...

AC in 5 go, kept getting Wrong answer #0 , because MIN_VAL i stored in array was too large

solve GSS1 before this

Very nice test cases , O(nm) brute force passes in 0.31s....

Except for that very nice question on range queries - AC in one go with segment tree

you can solve this with sqrt decomposition too.

GSS1 + Point update
