How to find the percentage of the number, the sum of the numbers, the percentage difference? Select the cell and press the combination of hot keys CTRL + SHIFT + 5. It is similar to the mathematical expression a choose b, except that instead of the number of such combinations, the actual combinations are returned. how can i find or calculate a list of all those possible combinations? it shouldnt be too long of a list because each combination should only use each number once and should be Since events 1, 2, 3, 4 and 5 are independent, total number of ways is product of the individual number ways of doing them. In our case, the best combination is a sum that is as close as possible to our goal number. While a simple brute force approach solves this for small numbers easuily, for large numbers even stroing the results is not trivial due to the huge number of results. The following program will print all possible combinations of additions from a given set of numbers so that they sum up to a given target number. by using recursion.
