Write Unit tests for both codes

Python Code:

def fibonacci(n):

if n <= 0:

return []

elif n == 1:

return [0]

elif n == 2:

return [0, 1]

else:

fib = [0, 1]

for i in range(2, n):

fib.append(fib[i-1] + fib[i-2])

return fib

Python Code:

def tower_of_hanoi(n, source, auxiliary, target):

if n == 1:

print("Move disk 1 from", source, "to", target)

else:

tower_of_hanoi(n-1, source, target, auxiliary)

print("Move disk", n, "from", source, "to", target)

tower_of_hanoi(n-1, auxiliary, source, target)
