What is a Padovan number?

Padovan numbers are numbers in the Padovan sequence. The Padovan sequence is a sequence of integers represented by the recurrence relation:

P(n) = P(n – 2) + P(n – 3)

Here, P(0) = P(1) = P(2) = 1.

For example, the 5th Padovan number.

P(5) = P(3) + P(2)

where P(3) = P(1) + P(0)

P(5) = P(3) + P(2) = P(1) + P(0) + P(2) = 1 + 1 + 1 = 3
