In which order do you need to hit some Deku Scrubs to open the first boss door in "Ocarina of Time"?

In order to open the first boss door in Ocarina of Time, the Deku Scrubs need to be hit in the following order: 2, 3, 1. This sequence is necessary because hitting the second Deku Scrub first allows him to reveal a platform leading to the third Deku Scrub. Once the third Deku Scrub is hit, he reveals another platform leading to the first Deku Scrub. Finally, hitting the first Deku Scrub opens the door to the boss room, allowing Link to proceed in his adventure.
