• stack : A collection based on the principle of adding elements and retrieving them in the opposite order – Last-In First-Out ("LIFO") – The elements are stored in order of insertion but we do not think of them as having indexes – The client can only add/remove/examine the last element added (the "top") • basic stack operations:
peek ? get the top data element of the stack without removing it isFull ? check if stack is full isEmpty ? check if stack is empty At all times we maintain a pointer to the last PUSHed data on the stack As this pointer always represents the top of the stack hence named top The top pointer provides top value of the stack
• "e stack is to the left of the dot the method name is to the right • In OCaml it’s seemingly backward: let s = MyStack empty in let s’ = MyStack push 1 s in let one = MyStack peek s’ • "e stack is an argument to every function (common idioms are last argument or ?rst argument) • Just a syntactic detail (boring)
a stack namely the LIFO property that links how elements are added and removed Furthermore the names can be changed without destroying the stack-edness of an abstraction For example a programmer might choose to use the names add or insert rather than push or use the names peek or inspect rather than top Other variations are also common
Stack limitations/idioms •You cannot access a stack's elements by index Stack s; for (int i = 0; i < s size(); i++) {do something with s[i]; // does not compile} •Instead you pull elements out of the stack one at a time •common pattern: Pop each element until the stack is empty // process (and empty!) an entire stack while (!s
