integers 1<=N<=100 representing the total number of products, 1
<= M<= 10000 the money Iserlohn gets, and 1<=K<=10
representing the sneaker brands. The following N lines each represents a
product with three positive integers 1<=a<=k, b and c,
0<=b,c<100000, meaning the brand’s number it belongs, the labeled
price, and the value of this product. Process to End Of File.
