HDOJ 4939 Stupid Tower Defense


It is obviously better to put red behind. dp [I] [j] indicates that there are j blue in the first I tower, and how many red are listed at the end.

Problem DescriptionFSF is addicted to a stupid tower defense game. the goal of tower defense games is to try to stop enemies from crossing a map by building traps to slow them down and towers which shoot at them as they pass.

The map is a line, which has n unit length. we can build only one tower on each unit length. the enemy takes t seconds on each unit length. and there are 3 kinds of tower in this game: The red tower, the green tower and the blue tower.

The red tower damage on the enemy x points per second when he passes through the tower.

The green tower damage on the enemy y points per second after he passes through the tower.

The blue tower let the enemy go slower than before (that is, the enemy takes more z second to pass an unit length, also, after he passes through the tower .)

Of course, if you are already pass through m green towers, you shoshould have got m * y damage per second. the same, if you are already pass through k blue towers, the enemy shoshould have took t + k * z seconds every unit length.

FSF now wants to know the maximum damage the enemy can get.
InputThere are multiply test cases.

The first line contains an integer T (T <= 100), indicates the number of cases.

Each test only contain 5 integers n, x, y, z, t (2 <= n <= 1500,0 <= x, y, z <= 60000,1 <= t <= 3)

OutputFor each case, you shoshould output "Case # C:" first, where C indicates the case number and counts from 1. then output the answer. for each test only one line which have one integer, the answer to this question.
Sample Input
12 4 3 2 1

Sample Output
Case #1: 12HintFor the first sample, the first tower is blue tower, and the second is red tower. So, the total damage is 4*(1+2)=12 damage points.
