ACME wants to extract ore from four different nonoverlapping mines. You are to choose these mines to maximize the total profit. Input. The first line contains an integer T (1 ≤ T ≤ 5), denoting the number of test cases. For each test case, the first line contains two positive integers R and C (2 ≤ R,C ≤ 100), denoting the number of rows and columns of a rectangular field. Each ...

Making plastic : extracting raw material. In 2012, million tons of plastic were used in France (44% of it was for packaging, a much higher percentage than construction or the car industry). This makes France the third biggest consumer of plastic in Europe, after Germany and Italy. Previously, a large portion of this waste (a little over 3 million tons) were sent to landfills ( tons) or ...

From ore to metal. What are "ores"? An ore is any naturallyoccurring source of a metal that you can economically extract the metal from. Aluminium, for example, is the most common metal in the Earth''s crust, occurring in all sorts of minerals. However, it isn''t economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite which contains ...
