Implement a stack in Go using a struct with a slice and Push/Pop methods for LIFO operations.
Implement a stack in Go by defining a struct with a slice and adding Push and Pop methods to manage the data.
type Stack struct {
items []int
}
func (s *Stack) Push(item int) {
s.items = append(s.items, item)
}
func (s *Stack) Pop() (int, bool) {
if len(s.items) == 0 {
return 0, false
}
index := len(s.items) - 1
item := s.items[index]
s.items = s.items[:index]
return item, true
}
A stack is a data structure that works like a pile of plates: you add items to the top and remove them from the top. This Last-In-First-Out (LIFO) approach is essential for tasks like tracking function calls or undo operations in software. You use it when the order of processing matters and the most recent item must be handled first.
