Stack & Queue

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

An educational data-structure playground that maintains BOTH a LIFO stack and a FIFO queue of ints side by side. Push/Pop the stack, Enqueue/Dequeue the queue, and Render shows both structures with the top/front element labeled, their sizes, and a one-line reminder of how LIFO differs from FIFO. Popping or dequeuing an empty structure panics (a cross-realm abort).

Realm path: gno.land/r/REPLACE_ADDR/stack

Example calls

# Stack (LIFO)
Push 1
Push 2
Push 3
Pop        # -> 3
Pop        # -> 2

# Queue (FIFO)
Enqueue 1
Enqueue 2
Enqueue 3
Dequeue    # -> 1
Dequeue    # -> 2

Via gnokey:

1gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/stack" -func Push     -args 42 ...
2gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/stack" -func Pop      ...
3gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/stack" -func Enqueue  -args 42 ...
4gnokey maketx call -pkgpath "gno.land/r/REPLACE_ADDR/stack" -func Dequeue  ...

Read the live view with Render (e.g. via gnokey query vm/qrender).

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 7

func Dequeue

crossing Action 
1func Dequeue(cur realm) int
source

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

func Enqueue

crossing Action 
1func Enqueue(cur realm, n int)
source

Enqueue adds n to the back of the FIFO queue.

func Pop

crossing Action 
1func Pop(cur realm) int
source

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

func Push

crossing Action 
1func Push(cur realm, n int)
source

Push adds n to the top of the LIFO stack.

func Render 

1func Render(path string) string
source

Render returns a Markdown view of both structures with top/front labeled, their sizes, and a one-line explanation of LIFO vs FIFO.
