It is. Description says: Assume the second parameter will be a string holding one of two values: 'value' and 'index'.

So we don't have to consider other cases. That behaviour is undefined, we can return whatever.

Nice ,short, and clean code congratulation !!

amazing @adrian-lui

i mean, yeah, but the task specifically asks you to include your points when calculating the class averange :p

Even when declarative approach is very keen on the eye it introduces a large overhead compared to just using sort with imperative looping... in my case its around 26ms overhead, compared to 0 abstraction solution that is under half of millisecond, its arround 8000% increase in execution time... For more info check my solution.

Adding yourPoints to the array will NOT change the result, if you think about it. It will change the average point but it will not change the fact that you are higher or lower than the average.

one of these days i might actually come up with a good solution haha

what is the equation doing in the Math.min brackets? I don't understand how the 0.05 and 0.25 work.

I feel myself dumb now

Can be done with BigDecimal rather than with String parsing

I added yourPoints to my answer, people just upvote the answers with the least lines so youre not likely to see top answers do it correctly

Nice Code !

Explain why I have an error
