This puzzle makes me a headache…
If there is an array where is integer values in it (let’s say numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
How you make a script what counts and shows all alternatives where four numbers sum(total) is example 40? One number can be use only one time.
Like example:
5 + 10 + 11+ 14 = 40
6 + 9 + 12 + 13 = 40
7 + 10 + 11 + 12 = 40
etc…
Quite puzzle, is it?
