Problem Description
Few days before a game of orienteering, Bell came to a mathematician to solve a big problem. Bell is preparing the dessert for the game. There are several different types of desserts such as small cookies, little grasshoppers and tiny mantises. Every type of dessert may provide different amounts of energy, and they all take up different size of space.
Other than obtaining the desserts, Bell also needs to consider moving them to the game arena. Different trucks may carry different amounts of desserts in size and of course they have different costs. However, you may split a single dessert into several parts and put them on different trucks, then assemble the parts at the game arena. Note that a dessert does not provide any energy if some part of it is missing.
Bell wants to know how much would it cost at least to provide desserts of a total energy of
p
Input
T(T≤10) representing the number of test cases.
For each test case there are three integers
n,m,p on the first line
(1≤n≤200,1≤m≤200,0≤p≤50000), representing the number of different desserts, the number of different trucks and the least energy required respectively.
The
i−th of the
n following lines contains three integers
ti,ui,vi(1≤ti≤100,1≤ui≤100,1≤vi≤100) indicating that the
i−th dessert can provide
tienergy, takes up space of size
ui and that Bell can prepare at most
vi of them.
On each of the next
m lines, there are also three integers
xj,yj,zj(1≤xj≤100,1≤yj≤100,1≤zj≤100) indicating that the
j−th truck can carry at most size of
xj , hiring each one costs
yj and that Bell can hire at most
zj
Output
50000. Otherwise, output
