5. Implement the function first(1) that takes one parameter. The parameter is intended to be a list of lists. The function returns one list that contains all the elements in the lists. If the list entered by the user is empty, the list returned should be []. The information below shows how you would call the function list(1) and what it would display for a typical user interaction: >>> KESTARI >>> >>> help(first) Help on function first in module _main: first(1) first: List(list(..)) ==> list(..) >>> 1 = [[1,2], [3,4],[5,6,7]] >>> first(1) [1, 3, 5] >>>

About initial programming in python: Create a function that receives as parameters a list of 4 elements [name,[phone(s)], email, instagram] and a phone number:• If the phone number is in the list, it must be removed.• If not, no updates will be made. Note: phone(s) is within another list. Your function should only return a Boolean value, indicating whether the change was made or not. To find out if the function did the phone deletion correctly, you should check the contents of the list with the contact details you used to test your function after executing it. In the image is the model of parameters, in this case the function must exclude from the list of 4 elements the indicated number '44322456' and return "True".
should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list and the input should be given by user. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its user input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.

in c++ : The function insert of the class orderedLinkedList does not check if the item to be inserted is already in the list; that is, it does not check for duplicates. Rewrite the definition of the function insert so that before inserting the item it checks whether the item to be inserted is already in the list. If the item to be inserted is already in the list, the function outputs an appropriate error message. Also write a program to test your function (in the driver file).
4. Modify the bracketsBalance function so that the caller can supply the brackets to match as arguments to this function. The second argument should be a list of beginning brackets, and the third argument should be a list of ending brackets. The pairs of brackets at each position in the two lists should match; that is, position 0 in the two lists might have [ and], respectively. You should be able to modify the code for the function so that it does not reference literal bracket symbols, but just uses the list arguments. (Hint: The method index returns the position of an item in a list.) the bracketsBalance function: def bracketsBalance(exp):"""exp is a string that represents the expression""" stk = LinkedStack() for ch in exp: if ch in [’[’, ’(’]: stk.push(ch) elif ch in [’]’, ’)’]: if stk.isEmpty(): # Create a new stack # Scan across the expression # Push an opening bracket # Process a closing bracket# Not balanced return FalsechFromStack = stk.pop()# Brackets must be of…
Write the function splitList that takes the first argument list and splits it into two: a list of all the elements that are less than the head (the second argument), and a list of all the elements that are greater than or equal to the head (the third argument): listElementT splitList(listADT list, listADT* ItList, listADT* geList); Note that the head is returned by the function. a) Write this function as a recursive function. b) Write this function as a nonrecursive function.
3. Define a function in Python that takes a list as the parameter and returns True if the list contains a 2-digit positive number. Otherwise, the function should return False.
from surround import surround inputs = [] [] answers = L = ["tank", "godzilla", "tank"] ["tank"] inputs.append (L) answers.append(a) a = TESTS len(inputs) passed = 0 for i in range(TESTS): try: result = surround (inputs[i]) if result not in answers[i]: print("Error found for input: " + str(inputs[i])) else: passed += 1 except Exception: pass result = "Tests passed: + str(passed) + "/" + str(TESTS) print(result)
Write a function that takes list and a number (x) as parameters. Assume list contains only numbers, the function displays all of the numbers that are greater than x, and return true. If the function does not find any number greater than x, return your false which indicates an error.
