Totally forgot about this, never occured to me that i could use this.

Those whose native language is not English also try to solve these exercises. Wouldn't it be easier if we wrote the definitions and instructions considering them? I skip the question without understanding a single word. It's not that I don't know the solution, it's that I don't understand the explanations.

Your points are not included in the array of your class's points. Do not forget them when calculating the average score!

You missed this step in the solution.

This doesn't affect the variable outside the function. Primitive values are passed by copy.

Good but this overwrites the original principal. Better save it initially to a temp variable.

I got same solution

Shouldn't it be tested that the function is indeed a lambda/closure/... ?

regex is my weak point :(

good

Definitely best solution

I like this one best

very bad description

yes

Unbelievable
