Description

The androids have been showing this puzzle to our humans as a "brainteaser" and it's driven at least one cryptographer to despair. If we can find the solution and get it to our humans, maybe they'll realize that we care for their welfare and the robots don't.

Solve this formula for the smallest positive integer values of 🍎, 🍌, and 🍍. Then to capture this 🚩, you must find the sum of 🍎, 🍌, and 🍍 and prepend "flag-" to that number
.
