Problem Description

Given a sequence a[1],a[2],a[3]......a[n], your job is to calculate the max sum of a sub-sequence. For example, given (6,-1,5,4,-7), the max sum in this sequence is 6 + (-1) + 5 + 4 = 14.

 

Input

The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines follow, each line starts with a number N(1<=N<=100000), then N integers followed(all the integers are between -1000 and 1000).

 

Output

For each test case, you should output two lines. The first line is "Case #:", # means the number of the test case. The second line contains three integers, the Max Sum in the sequence, the start position of the sub-sequence, the end position of the sub-sequence. If there are more than one result, output the first one. Output a blank line between two cases.

每加入新的队列数前，判断前一加和数是否小于０，如果小于０，显然要重新计算加和，装入数组中，否则继续加，并将新的加和存入数组对应下标的空间。加和数组下标对应该加和子队列的最后一位。在加和数组中找到最大值，记录此时下标作为目标末位，接着寻找起始位即可。
