Challenge description:

Ken Thompson has a new programming language he is trying to promote so he has written a program that will give you a flag when you run it. He promises this new language can be installed on Mac OS X, Linux, or Windows. Can you find the flag?

Download file: gobig.go

Solution

We are given a .go file. Simply running the file in go reveals the flag.

$ go run gobig.go
