Consider the recurrence relation an=n2an1an2an=n2an1an2 with initial conditions a0=1a0=1 and a1=2a1=2. Write a Python function called sequence_slayer that takes a nonnegative integer argument NN less than 50 and returns the NN-th term in the sequence defined by the above recurrence relation. For example, if N=2N=2, your function should return sequence_slayer(2) = 7, because aN=a2=(2)2(2)(1)=7aN=a2=(2)2(2)(1)=7.

For example:

Test	Result
print(sequence_slayer(2))	7
print(sequence_slayer(3))	61
print(sequence_slayer(8))	2722564729
