Coding problem1

One coding question medium level.
The second was a puzzle. I wasn’t familiar with this puzzle at that time. So interviewer saw all my thinking processes.
puzzle was: 
We have two water jugs, one measures 4 Gallons (4G) while the other measure 9 Gallons (9G). But there is no measuring label mentioned on either of these two jugs i.e. we cannot know the exact amount filled in the jug. Now, assuming there is an infinite amount of water supply, can we measure all 1G, 2G, 3G…….. upto 9G using these unmarked jugs.
Hint: We can empty the jugs, and transfer water from one jug to other.
Then the interviewer asked about my project like what is the concept of the project, technologies used, etc.
