Case contract

Diving dive score. scores are judge marks as strings from 0 to 10 in half points; any other mark returns "invalid mark <s>". A 5-judge panel drops the single highest and lowest marks, a 7-judge panel the two highest and two lowest; any other panel size returns "invalid panel". The three remaining marks are summed and multiplied by the degree of difficulty dd (a decimal string); return the exact result with two decimals.

Why this case matters

Meet management systems compute dive scores from judge panels of different sizes.
