its pretty helpful when creating your first template, although i removed most of the stuff, it was still a great reference, thank you!

thanks

pretty helpful.

what is the write(tc); ?
Thanks

W

thanks. but i think there's an issue at line 25

When I copied the code, it's showing that readInt is undefined, and write—could you please help?

bro how did you solve this issue?
