Using Python. Write a function clean2(aList) that takes a list of integers aList as argument, and modifies this list, such as multiple occurrences of values have been removed. The procedure does not return a list: it modifies its argument (reference aList). 3 For instance, the following statements: al = [1,2,3,4,4,4,5,1,2,1,5] print(al) clean2(al) print(al) print the following result (a different order of values is acceptable): [1,2,3,4,4,4,5,1,2,1,5] [1,2,3,4,5]

For Python [25 pts] Write the method divisorList(aList, divisor) that takes in a list with elements of any data type and a divisor which is in the form of an integer. The output is a sorted list of only the integers that are divisible by the divisor. Example: divisorList([1, 1, 12, 'a', 90, 34], 2) will return [12, 34, 90] since 12, 90, and 34 are all divisible by two. Note that the returned list is sorted from smallest to...

Write the function deep_contains. It takes as input a number and a list. That list might contain lists as elements, and those lists might contain lists, etc. The deep_contains' function should return a Boolean indicating whether the number is contained inputted list, or a sublist of it, or a sublist of that, and so forth. For example: deep_contains (3, (1,3,5]) returns True deep_contains(3, 11, [3,5]]) returns True deep_contains (3, 1, [[3,4],5),6]) returns True deep_contains (2, (1,3,5]) returns False This function...

Please write the code in a text editor and explain thank you! 1. LINKED-LIST: Implement a function that finds if a given value is present in a linked-list. The function should look for the first occurrence of the value and return a true if the value is present or false if it is not present in the list. Your code should work on a linked-list of any size including an empty list. Your solution must be RECURSIVE. Non-recursive solutions will...

MATLAB QUESTION Write a MATLAB function called vector_input that takes no inputs and returns no outputs. Instead, when called, it gives control to the user and asks the user to input a length-3 vector. Then the function prints: The sum of ___, ____, and ____ is ____. [new line] where the first three blanks are filled by each element in input vector, and the last blank is the sum of all three elements.
Write the function deep_contains. It takes as input a number and a list.
