Yeah this is great! I would be happy to work with this person :]

Man, you deserve respect, well done!

Great solution! I initially tried implementing something similar, but couldn't figure out the right conditions for the loop... I ended up with something way less efficient lol

Easily understandable. Learned from this. Thanks!

I believe the only parts missing are the definitions of constants for the cost of a day and the various discounts. Perhaps also consider using the ternary operator in the discountRate function.

"more code" isn't a big deal if it's not increasing complexity. sure he could have perhaps used ternaries instead of if-else, but what i see at work here is the prevailing desirability of standard syntax.

I really do like it!

Great answer, its really well thought out!

We have the same logic but I didn't know you can put multiple conditionals on for loop. Thanks for the knowledge.

Yes so it will check if k > 0 on every iteration of the loop.
Perhaps an initial check would be better since it doesn't change.

That was really clever how you added i + k to the slice method to group two array elements at each time. I'm going to need use that in my code.

k > 0 is in the conditional part of the for loop

k > 0 is in the conditional part of the loop.

maybe i'm crazy but does this work? "i<=strarr.length-k" is a mistake, it should be "i<=strarr.length-(k-1)" instead, because in a given solution function does not analise the last array item
