There are 6 currencies with a nominal value. The smallest value is 1, and the minimum number of currencies is calculated as 1 .. 100. The maximum value and their average value are output. Subtraction can be used. For example, 6 = 1 + 2 + 3, 6 = 7-1, then the minimum number of currencies for 6 is 2. It is a backpack with no lower limit. You can open the volume array to 3000 + (after testing ).View code 1 program pku1252(input,output); 2 var 3 f
