What is the brain teaser for least?

The brain teaser for "least" could involve a riddle or question that challenges one's ability to think critically about minimal values or quantities. For example: "What is the least number of times you can subtract 1 from the number 10 to end up with a negative number?" The answer is one time, as subtracting 1 from 10 gives you 9, and repeating that process leads to a negative number only after further subtractions. This kind of puzzle encourages lateral thinking and engages problem-solving skills.
