What is: Fill the 5-gallon jug. Pour into the 3-gallon jug, leaving 2 gallons in the 5. Empty the 3-gallon jug. Pour the 2 gallons from the 5 into the 3. Refill the 5-gallon jug. Pour from the 5 into the 3 (which already has 2) until the 3 is full — that takes 1 gallon. You're left with exactly 4 gallons in the 5-gallon jug.
