Stacks in Go

Implementing a stack in Go

It is now time to look at the implementation of a stack in Go. This will be illustrated in the stack.go source file. Once again, a linked list will be used for implementing the stack. As you know, you will need two functions: one function named Push() for putting things on the stack and...
