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

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

func Enqueue
crossing ActionEnqueue adds n to the back of the FIFO queue.
func Pop
crossing ActionPop removes and returns the top element of the LIFO stack. It panics (a cross-realm abort) if the stack is empty.
func Push
crossing ActionPush adds n to the top of the LIFO stack.
func QueueSize
ActionQueueSize returns the number of elements in the FIFO queue.
func Render
Render returns a Markdown view of both structures with top/front labeled, their sizes, and a one-line explanation of LIFO vs FIFO.
func StackSize
ActionStackSize returns the number of elements in the LIFO stack.
