It sets up 2 variables difficulty
which stores the current difficulty
and maxDifficulty
which defines the highest difficulty setting
if the difficulty is lower than max difficulty it runs PlayGameAtDifficulty
I guess the next part sees whether you pass or fail (not sure how)
and then it adds a +1 (assuming ++
means add 1) to difficulty variable
then it also says “congratulations” and all that.
i dont know what return 0 means
