Dancing (Posted on 2003-02-16) Difficulty: 2 of 5
In a popular dancing game there are 4 directions: up, down, left, right. In the game these arrows may appear once every quarter-note or eight-note. Also two arrows may appear at the same time in the same beat. Three or four arrows cannot.

In a song that is 1 minute long and plays at 1 bar(4 quarter notes) every 4 seconds, what are the total possible number of different dances that can exist.

There are 120 segments of the song each with 11 possible arrow possibilities. None, up, down, left, right and the 6 combinations.
