Sample

FIFO queue push, shift, isEmpty, and clear operations

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. FIFO instantiates an empty queue with length 0 and isEmpty returning true
  2. FIFO push adds elements to the queue in FIFO order and updates length
  3. FIFO shift removes and returns elements in first-in first-out order until empty
  4. FIFO clear resets queue state and length back to zero
