    Default Help me with a very basic math algorithm?

    There are 3 judges, 3 rounds and 3 judges in this diving competition.

    There is also a degree of difficulty from 1 to 3.5 that multiplies with the added score

    Suppose Contestant 1 would go first:

    Degree of difficulty = 2
    Judge 1 would give 9
    Judge 2 would give 5
    Judge 3 would give 1

    Now the highest and lowest scores are removed max and min (don't ask why)

    So the total would be 10 for Contestant1



    My programs calculation is - total [0] = total [0] + ((score [0] - max [0] - min [0]) * degree);

    Can you correct my formula or tell me something else is wrong?

    What is in the score array?
    What is in the total array when the posted line of code is executed? Why is total[0] to the right of the =?

    What value does your formula compute?

    Write out the equation on a piece of paper replacing the variables with their values and see if it makes sense.

    Score array is what the three judges input. The total array is the scores added up (all 3) multiplied by the degree - the lowest and highest number.

    I dont really understand what you mean why is total [0] right of line - shouldn't it always be? I'm new to programming and keep it simple.

    total [0] = total [0] + ((score [0] - max [0] - min [0]) * degree);

    Why is the total[0] in red where it is in the formula? What value will it have before the statement is executed?

    What value is in the score[0] variable?

    Write out the statement replacing the variables with their values and post it here.

    Total is 0,degree is 2 and score - one is 1, two is 5 and three is 9. So max would be 9 and min would be 0. That way it should be 10.

    Sorry if I bolded

    Maybe I should just go to the first forum - whats wrong with my code..

    Why do you use score[0] in your formula? Is that one of the three scores?
    What is in the total, max and min arrays? How many elements are in the arrays? Why are those variables arrays?
