Find a value in a small lookup table
Arduino / C: A linear scan is simple and predictable for a small fixed array.
Arduino / C✓ Tested
Find values missing from another collection
Python: Use a set difference to identify requested IDs absent from the available IDs.
Python✓ Tested
Fit as many columns as possible
Use auto-fit and minmax for a CSS grid that responds to its available width.
CSS✓ Tested
Force a disposable container to stop
Docker / Compose: kill sends SIGKILL by default without a graceful shutdown interval.
Docker / Compose✓ Tested
Format several integers in a fixed buffer
Arduino / C: snprintf limits writes to the buffer size and includes a terminating null byte.
Arduino / C✓ Tested
Generate and measure a short output pulse
Arduino / C: delayMicroseconds can create a short blocking pulse on an output pin.
Arduino / C✓ Tested
Give a read-only container temporary storage
Docker / Compose: Give a read-only container temporary storage using a locally available Ubuntu image.
Docker / Compose✓ Tested
Give a read-only service writable scratch space
Docker / Compose: A tmpfs mount provides temporary storage independent of the root filesystem.
Docker / Compose✓ Tested
Give an existing image another tag
Docker / Compose: Tagging adds a reference without copying the image layers.
Docker / Compose✓ Tested
Give an LED pin a constant name
Arduino / C: Use const to name the built-in LED pin and reuse it in output instructions.
Arduino / C✓ Tested
Group related readings in a struct
Arduino / C: A struct keeps a sample’s fields together without dynamic allocation.
Arduino / C✓ Tested
Grow an allocation without losing it on failure
C: Assign realloc to a temporary pointer so the original allocation remains available if growth fails.
C✓ Tested
