Uphill and Downhill X22657
We have the altitude data recorded by a watch during a walk. The clock registers, at each unit of time, the height in meters above sea level. Write a program such that, given the sequence of altitudes, calculates the following three values:
The cumulative positive slope. That is, the accumulated height gains on the walk.
The cumulative negative slope. That is, the accumulated loss of height on the walk.
The highest cumulative slope in an uphill section. An uphill section is characterized by not having any elevation loss.
For example, given the sequence of heights 1 2 2 4 3 5 4, the cumulative positive slope is 5, the cumulative negative slope is 2, and the highest cumulative slope in an uphill section is 3.

Input
On entry there is a non-negative integer followed by a series of cases. Each case consists of a sequence of heights. Each height is a nonnegative integer. Right after the sequence appears the -1 mark.
Output
For each case, a line with the cumulative positive slope, the cumulative negative slope, and the highest cumulative slope in an uphill section.
