Question
Implement a __setitem__ function that also supports negative indices. For example:
W = L2(Node(10, Node(20, Node(30))))
print W
[ 10, 20, 30 ]
W[1]=25
print W
[ 10, 25, 30 ]
W[-1]=35
print W
[ 10, 25, 35 ]
Complete the code:
def L2(*args,**kwargs):
class L2_class(L):
def __getitem__(self, idx):
<... YOUR CODE HERE ...>
def __setitem__(self, idx, value):
<... YOUR CODE HERE ...>
return L2_class(*args,**kwargs)
W = L2(Node(10, Node(20, Node(30))))
print(W)
W[1]=25
print(W)
W[-1]=35
print(W)
