odd-even
Switching between parities
Odd-even describes a system that alternates between odd and even numbers, typically for rationing or access.
During fuel shortages, odd-even rationing allows drivers to buy gas only on days matching their license plate's last digit: Odd plates fill up on odd-numbered days.
The scheme distributes demand and reduces lines by splitting eligible customers.
