The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted. The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here. Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…
Implement the following two sorting algorithms in a program called p3.py. Write two separate functions for these algorithms. Both functions must take a list of integers as the input parameter.1) Bogosort: first shuffle the list argument (i.e., randomize the positions of every element) and then check to see if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.2) Bozosort: choose two elements in the list at random, swap them, and then check if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.Write a main() function and call both sorting functions using the same list as their arguments. The list can be of any size (try a small list first). Does any of your algorithms terminate? If yes, count the number of iterations it uses to sort the list. Does it always use the same number of repetitions? If…
This chapter's bubble sort method is less efficient than it could be. If a pass through the list is done without swapping any components, the list is sorted and there is no reason to continue. Change this algorithm to terminate as soon as it recognises that the list is sorted. A break statement should not be used.This chapter's bubble sort method is less efficient than it could be.

We will start by finding the largest value. Initially, we assume that the first element in the list is the largest element and create a variable maxValue that is initialized to the first element in the array. We then compare the element that maxValue is storing with every element in the list. Whenever we find an element in the array larger than the element that maxValue is storing, we update maxValue so that it stores the value of the newer larger element. Algorithm ArrayLargestElement Declare and initialize maxValue to the first element in the array. Use a FOR loop to traverse the array. // You already checked the first element, so you should start the loop at the second element. If the element at this index is larger than maxValue Update maxValue Output maxValue. Write a program MyArray_ABC that declares an array containing the following elements: 45, 38, 27, 46, 81, 72, 56, 61, 20, 48, 76, 91, 57, 35, and 78, and outputs the largest value. PART B.

1. Consider the following search algorithm for sorted lists: Starting from the first element, the algorithm jumps K elements at once until finding or passing the element we are searching for. If it passes that element, then starts jumping back previous items one by one. If there are not enough elements for the last jump, then it jumps to the last element. Example: Let K=3 – we are searching for 5 1 2 3 4 5 7 8 9. 10 a. Write a pseudocode or draw a flowchart. b. Develop a Python program in a function form with parameters K and searchFor c. Try the algorithm for (i) K=4, searchFor=13 & (ii) K=5, searchFor=44 considering the following list: [2,7,8,9,11,13,16,21,28,29,30,34,37,39,41,44,47,48]| d. Considering the list in (c), which K-searchFor combination would lead to the highest number of jumps?
Write a program that animates the insertion-sort algorithm. Create a list that consists of 20 distinct numbers from 1 to 20 in a random order. The elements are displayed in a histogram, as shown in Figure 10.21. Clicking the Step button causes the program to perform an iteration of the outerloop in the algorithm and repaints the histogram for the new list. Color the last bar in the sorted sublist. When the algorithm is finished, display a dialog box to inform the user. Clicking the Reset button creates a new random list for a new start.
Consider the Double Linked List that is given below, where each box represents a ‘node’ type with two fields: integer data and a node type reference ‘next’ that points to the next node in the list. a) Write an algorithm to count all nodes that contain an odd number. b) Write an algorithm to print all nodes that contain an even number in the reverse direction of the list.
That's enough for you! def first_preceded_by_smaller(items, k=1): Given a list of items, find and return the value of the first element for which at least k smaller elements precede that element in items. If no such element exists inside the list, this function should return None.

Selection sort is a sorting algorithm, like Bubble sort which you saw in the previous module. Selection sort works as follows: Selection sort divides the input list into two parts: a sublist of sorted items (left part) and a sublist of still unsorted items (right part). Initially, the sorted sublist is empty and the whole input consists of the unsorted sublist. To fill the sorted sublist, the algorithm computes the (index of) the minimum of the unsorted sublist and swaps the first unsorted element and the minimum element (if the minimum is already the first element, nothing happens). Afterward, the sorted sublist is one bigger. This continues until the unsorted sublist is empty and the entire input is sorted. Example: Sorted sublist Unsorted sublist Least element in unsorted list (11, 25, 12, 22, 64) 11 |(11) (25, 12, 22, 64) 12 |(11, 12) (25, 22, 64) 22 |(11, 12, 22) (25, 64) 25 |(11, 12, 22, 25) (64) 64 (11, 12, 22, 25, 64) Implement this algorithm.

Select which of the following statements about searching for items in a list is incorrect. Group of answer choices 1. In an unsorted list, if the item is not present in the list, we will need to check every single item. In a sorted list, if we start the search at the smallest item, at most we would only need to check all items smaller than the target. If we get to an item larger than the target we can end our search early. This would make searching faster in the sorted list. 2. Sorting a list only makes sense for primitive types (ints, doubles) and Strings but not objects. For this reason we cannot sort a list of objects, and will always have to check each object in a list when we search for a target object. 3. In an unsorted list you need to check each item, to see if it is the item you want. If the list is sorted you can look at the middle item and then you can direct your search to the relevant portion of the list (higher or lower). This is called binary search. This will…
Assume, you have been given two lists. Your task is to multiply the first element of the first list, to the last element of the second list and store them in another list. Then, again multiply the second element of the first list, to the second last element of the second list, and so on. If any of your lists is out of element, and another list has some elements remaining, then just append the remaining elements to your final list and print the list.================================================ Given lists 1:list_one = [1, 4, 7, 5]list_two = [6, 1, 3, 9] Sample Output 1:[9, 12, 7, 30] Explanation 01: Here, from list_one’s 1st element, 1 has been multiplied with the last element of list_two 9. So, the product 1X9 =9 has been added to the answer. Then, from list_one’s 2nd element, 4 has been multiplied with the 2nd the last element of list_two 3.
