The following function is designed to take in a nested list structure of unknown depth, where each element at every level is either an integer or a list. The function should return a copy of the nested list structure, but with all integer values increased by 1.Fill in the blanks in the function such that it works as intended.```pythondef deep_add(collection): if isinstance(collection, int): # Checks if collection is an int return _____ elif collection == []: return _____ else: return [deep_add(collection[0])] + _____```**Explanation of the Code:**- The function `deep_add` processes a nested list.- It checks if the current item, `collection`, is an integer. If it is, it returns the integer increased by 1.- If `collection` is an empty list, it simply returns the empty list.- If `collection` is a non-empty list, it recursively processes the first element, combines it with the result of processing the rest of the list, and returns the modified list.This function effectively traverses the nested list structure and increments each integer by one, maintaining the original list's structure. **Examples:**```python>>> deep_add([[3, -4, [15]], 0, [[[1]], 61]])[[4, -3, [16]], 1, [[[2]], 62]]>>> deep_add([1, [2, 3], [], [4, 5, [6]], 1])[2, [3, 4], [], [5, 6, [7]], 2]>>> deep_add([[[[7]]]])[[[[8]]]]```These examples illustrate the use of the `deep_add` function, which increments each integer within deeply nested lists by one. The function traverses all levels of nested lists and applies the addition recursively, updating each integer encountered.

[ ] [] power In the cell below, you are to write a function "power(list)" that takes in a list as its input, and then returns the power set of that list. You may assume that the input will not have any duplicates (i.e., it's a set). After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (power ( ["A", "B"]), power ( ["A", "B", "C"])) + Code + Markdown This should return [[], ["A"], ["B"], ["A", "B"]] [[], ["A"], ["B"], ["C"], ["A", "B"], ["A", "C"], ["B", "C"], ["A", "B", "C"]] (the order in which the 'sets' appear does not matter, just that they are all there) Python Python
