def func(n):

first3 = {1:1, 2:2, 3:4}

if n in first3.keys():

return first3[n]

else:

return func(n-1) + func(n-2) + func(n-3)

print(func(5))

def func(a, b):

return a + b

a = 3

b = 4

c = func(a, b)

print(c)

请分析代码的输出结果：________。

def func(a, b):

return a + b

def wrapper(f, a, b):

return f(a, b) - 1

print(wrapper(func, 2, 3))

该代码的输出结果是____。
