// Homework 26, challenge: Stack.
//
// Build a stack struct that holds strings:
//   items     -- a []string field
//   push(v)   -- gives back a stack with v on top
//   pop()     -- gives back a stack without the top item, and the top item
//   peek()    -- returns the top item and true, or "" and false if empty
//   size()    -- returns the number of items
//
// Push three values, then call size, peek, pop, pop, size in that order, and
// print the results.
//
// Run with: go run exercises/26/homework/04-stack.go
