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
