HINTS: Twelve Computer Scientists Challenge

less than 1 minute read


Please highlight to check the hints.

Hint #1:
There are at least 2 ACTUAL solutions, which don’t involve beating someone with the seesaw nor prototyping a digital weight scale nor asking the 12 computer scientists to brainstorm with you.

Hint #2:
Think about the base case, which means, if you can only use the seesaw once, under what conditions (how many candidates, etc) can you identify the one with different weight.

Hint #3:
The first step should be dividing 12 computer scientists into 3 groups of 4 people.
