Question

PYTHON Define a function reverseNestedList(...) which receives one possibly nested list (lst1) and returns the reverse of both the given list and any nested lists inside it.

Note that the testing inputs will not include lists that are nested more than twice (a list in a list in a list ++...) [[[...],1], 1]

Good luck!

As an example, the following code fragment:

lst1 = [[1, 2], [3, 4]] print(reverseNestedList(lst1))

should produce the output:

[[4, 3], [2, 1]]

Answer 1

def reverseNestedList(lst):
    res = []
    i = len(lst)-1
    while(i>=0):
        tmp = []
        j = len(lst[i])-1
        while(j>=0):
            tmp.append(lst[i][j])
            j-=1
        res.append(tmp)
        i-=1
    return res

# Testing
lst1 = [[1, 2], [3, 4]]
print(reverseNestedList(lst1))
