Question

Given the following code snippet, find the following:
1) Recurrence relation of func (x,y) when x>0 and length of y is n. Express in the form below:
T(x,n) = T(?) + O(?)

For 2-3, consider worst-case scenario and initial value of y as [1]
2) Time complexity of func (x,y)
3) Space Complexity and Auxiliary Space Complexity of func (x,y)

1 v def func (x, y=[1]):
2 v
if x <= 1:
3
return y
y_2 = [y[integer] + y[integer+1] for integer in range (len(y)-1)]
return function(x-1, [1] + y_2 + [1])
