Sources for "The Go Programming Language" by Donovan and Kernighan

My sources for the leaning GoLang , book "The Go Programming Language" by Donovan and Kernighan, folders split is by chapter in the book

Sometimes they repeat the original code, and sometimes there are going to be soime variations to test my own understanding
