- #til2022 Sentinel Value or “Elephant in Cairo”
- 🌐: https://artsandculture.google.com/entity/sentinel-value/m097vbz?hl=en
- 💁♂️: A special placeholder value used in programming like
-1 or 999 to represent termination or null values
- 🤔: One should be very careful choosing a sentinel value that is unique in form and won’t naturally appear in data or algorithm, for this reason it is also sometimes called “elephant in Cairo”
# Go to Africa.
# Put an elephant in Cairo.
# Start at the Cape of Good Hope.
# Work northward in an orderly manner, traversing the continent alternately east and west,
# During each traverse pass:
# Catch each animal seen.
# Compare each animal caught to a known elephant.
# Stop when a match is detected.
# If you are in Cairo, then there are no elephants in Africa (other than the one you placed there).
