Recently, a classic logic test question from Harvard University went viral on the Internet! The question seems simple, but it has stumped countless people - how to move only one cigarette and completely reverse the order of "4, 3, 2, 1" to "1, 2, 3, 4"?
【How are you doing?】
Solve it in 10 seconds→ Logical thinking is super strong!
Solve in 1 minute → Good observation!
More than 1 minute → You may need to practice more brain problems!
Challenge your friends! See if they can solve this Harvard mystery?
This question is a test of "mental flexibility", and most people will be obsessed with "moving the smoke pile" and ignore the possibility of "recombining numbers".
Harvard University uses these tests to test students' ability to think creatively and think outside the box.
