Thanks man! I was not sure how to get it to read googles input but only from a file, this really helped.

Hey, nice and helpful video!

I have a question:
sum+= +arr[k];
what is the purpose of + sign before arr[k] ?

[itspravas]

why the path is 0 in fs.readFileSync(path[, options]) function ?
how you get to know which path google is using ?
is the input during submission is via commandline or text input ?

Do you use JS on other competitive programming sites like codeforces or some of the other ones?
