What happens when you add an entry into position 4 into a List? Select one: a. If the List has 4 or more entries, entries in positions 4 and up will move over spot to make room for the new entry to be added to position 4 b. All of these c. If the List has 2 or fewer entries, an IndexOutOfBoundsExecption is thrown d. If the List has exactly 3 entries, the new entry will be added to the end of th List

Baby Names: Each year, the government releases a list of the 10,000 most common baby namesand their frequencies (the number of babies with that name). The only problem with this is thatsome names have multiple spellings. For example, "John" and ''.Jon" are essentially the same namebut would be listed separately in the list. Given two lists, one of names/frequencies and the otherof pairs of equivalent names, write an algorithm to print a new list of the true frequency of eachname. Note that if John and Jon are synonyms, and Jon and Johnny are synonyms, then John andJohnny are synonyms. (It is both transitive and symmetric.) In the final list, any name can be usedas the "real" name.EXAMPLEInput:Names: John (15), Jon (12), Chris (13), Kris (4), Christopher (19)Synonyms: (Jon, John), (John, Johnny), (Chris, Kris), (Chris, Christopher)Output: John (27), Kris (36)
Python write a program in python that plays the game of Hangman. When the user plays Hangman, the computer first selects a secret word at random from a list built into the program. The program then prints out a row of dashes asks the user to guess a letter. If the user guesses a letter that is in the word, the word is redisplayed with all instances of that letter shown in the correct positions, along with any letters correctly guessed on previous turns. If the letter does not appear in the word, the user is charged with an incorrect guess. The user keeps guessing letters until either: * the user has correctly guessed all the letters in the word or * the user has made eight incorrect guesses. one for each letter in the secret word and Hangman comes from the fact that incorrect guesses are recorded by drawing an evolving picture of the user being hanged at a scaffold. For each incorrect guess, a new part of a stick-figure body the head, then the body, then each arm, each leg, and finally…
What happens when you remove the entry from position 4 from a List? Select one: a. All of these b. The entry in the 4th position is returned (if there was a 4th entry) c. If the List has 3 or fewer entries, an IndexOutOfBoundsException is thrown d. If the List has 5 or more entries, the entries in positions 5 and up will move up 1 spot earlier to close up the gap vacated by removing the 4th entry
of range. 3. Use the method swap that you wrote in Exercise 2 to write a method that reverses the order of the items in a list alist.
The function that will a single items to the list is Oextend (...) Oadd(...) Oappend(...) Olengthen(...)
This is a linked list node class Node { public: int data; Node *next; }; Using the above code write the following functions. Please test in the main function of your program. Please upload all code that you write. 1. Adding and removing a node 2. Removing ever third node 3. Adding the complete list at the end. if you had a list 1,2,3 the new list will be 1,2,3,1,2,3 4. Write a function to find the average of the list 5. Write a function that takes in a list as a parameter and adds it to the current list. This Node add will only happen if list 1 element is less then list 2 element. Example List 1 - 1,2,3 List 2 - 3,1,4 New List - 4,2,7 - It only adds if L2 > L1 List all assumptions.
3. A list of numbers is considered increasing if each value after the first is greater than or equal to the preceding value. The following procedure is intended to return true if numberList is increasing and return false otherwise. Assume that numberList contains at least two elements. PROCEDURE isIncreasing(numberList) Tue 61 Line 1: Line 2: { Line 3: count 2 Line 4: REPEAT UNTIL(count > LENGTH(numberList)) Line 5: } IF(numberList[count] =. a. b. Lines 10 and 11 should be interchanged. d. In line 3, 2 should be changed to 1. 3.
statistics.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then print the mean, median, and standard deviation of the list. The mean is the average of the numbers. The median is the “middle” value if n is odd, or the average of the two “middle” values if n is even. The standard deviation is the average amount of variability For example: $ python3 statistics.py154102-12345mean: 7.75median: 7standard deviation: 5.909032633745278
There are two static lists A and B containing the following data: A: 2,5,9,14,15,7,20,17,30 B: 14,2,9,13,37,8,7,28 1. Write an algorithm that create a list C that contains only those elements that are common in list A and B 2. Write an algorithm that create a list D that contains all elements of A as well as B ensuring that there is no repetition of elements 3. For Question 1, calculate the running time to create and fill the list C Note: Only use operations of List A and List B for designing algorithms in part (a) and (b)
1. Write a game of rock paper scissors, one of the choices will be from the user and the other from the computer (use random) Print results for each game.Play the games in a row until you exit the game. Explain each step as comment.Game rules:Rock crushes scissors, you win.Paper covers rock, you win.Scissors cut paper, you win. 2. Write a program that sorts a list in ascending order. Don’t use sort method.Ask user number of list elements (at least 10 elements)Enter all elements from keyboard and printed.Sort your list. 3. Write a code for craps game. Craps is a dice game in which the players make wagers on the outcome of the roll, or a series of rolls, of a pair of dice.The rules of the dice game craps are as follows:You roll two dice. Each die has six faces, which contain one, two, three, four, five and six spots, respectively. After the dice have come to rest, the sum of the spots on the two upward faces is calculated. If the sum is 7 or 11 on the first throw, you win and play is…
Several of the programming exercises in this section ask you to find the mean and median value in a list. Recall that the mean is the arithmetic average and that that median is the middle value in an ordered list. When a list contains an odd number of values, the median is the value in the middle position. When a list contains an even number of values, the median is the mean of the values in the two middle positions. Chapter 2 described the remainder operator which you can use to determine whether a number is even or odd. When a number is divided by 2, the remainder is 0 if the number is even. Design an application that accepts 10 numbers and displays them in descending order.
