this problem is similar to that of the movie "Die Hard" with Bruce Willis and Samuel L Jackson. first, fill up with water the 3L bucket. transfer it to 5L bucket. fill the 3L bucket with the remaining 2L of water. mark the 3L bucket where 2L of water measures. fill up the 3L bucket with water from the 5L bucket. drain the water from the 3L bucket down to the mark. fill with the remaining 2L of water in 3L bucket into the 5L bucket which has 2L of water remaining. and the problem is solved, you get exactly 4L of water in 5L bucket.
