stack package

Overview

Package stack is an educational data-structure playground that keeps BOTH a LIFO stack and a FIFO queue of ints, so you can compare how the two behave.

Functions

Dequeue

func Dequeue(cur realm) int

Dequeue removes and returns the front element of the FIFO queue. It panics (a cross-realm abort) if the queue is empty.

Command

# WARNING: This command is running in an INSECURE mode.
# It is strongly recommended to use a hardware device for signing
# and avoid trusting any computer connected to the internet,
# as your private keys could be exposed.

Enqueue

func Enqueue(cur realm, n int)

Enqueue adds n to the back of the FIFO queue.

Pop

func Pop(cur realm) int

Pop removes and returns the top element of the LIFO stack. It panics (a cross-realm abort) if the stack is empty.
