Part 2: Catalan Numbers (8 points) The Catalan Numbers are a sequence of positive integers, similar to the Fibonacci sequence. The definition of the Catalan Numbers is: . Co = 1 . Cn+1 = 2(2n+1) Cn n+2 So, the first few Catalan Numbers for n = 0, 1, 2, 3, 4, 5, 6 are: n 0 1 2 3 4 5 6 Cn 1 1 2 5 14 42 132 Complete the a function catalan_numbers, which takes in an integer n and returns a list of the first n + 1 Catalan Numbers. Co is the first Catalan Number, in our case.
