Algorithm based on code

[ubi_ct83]

hi guys,
i really need help on this problem. i have a code, but i need to convert it to algorithm.but i dont know how since im still new in this programming matter. hope u guys can help me please....
thanks for advance.

public static void calculateTotalTupples(int p, int s, String set)
     {
        int n = p, r = s;
        int[] value = new int[n];

        StringTokenizer v = new StringTokenizer (set,",");
        int i=0;
        while(v.hasMoreTokens())
        {
            value[i] = Integer.parseInt(v.nextToken());
            i++;
        }


        int total =0;

        CombinationGenerator gen = new CombinationGenerator(n,r);

        while(gen.hasMore())
        {
            int[] comb = gen.getNext();

            int totalElement =1;
            for(int j=0;j<comb.length;j++)
            {
                totalElement *= value[comb[j]];

            }

            total += totalElement;

         }

        tupples = total;

     }
