number if ‘i’ is a factor ‘n’. Given two lists of numbers l1 and l2 form a list l3 by inserting factor indexed numbers of l1 and l2. Intialize index to ‘0’ visit elements of l1 and l2 at index, if one of them is factored indexed insert and increment index and go till end of the list. If both of them are factor indexed then insert element of l1 at index and then element of l2 at index and increment index. If end of one of the list is reached then add elements of other list to l3 if they are factor indexed. After construction of l3, Print the numbers which continues to be factor indexed in l3.

A number ‘n’ in a list at index ‘i’ (human indexing) is said to be a factor indexed number if ‘i’ is a factor ‘n’. Given two lists of numbers l1 and l2 form a list l3 by inserting factor indexed numbers of l1 and l2. Intialize index to ‘0’ visit elements of l1 and l2 at index, if one of them is factored indexed insert and increment index and go till end of the list. If both of them are factor indexed then insert element of l1 at index and then element of l2 at index and increment index. If end of one of the list is reached then add elements of other list to l3 if they are factor indexed. After construction of l3, Print the numbers which continues to be factor indexed in l3.For example, if l1 contains 15, 12, 17, 32, 26, 42 and l2 contains 45, 34, 64, 80 then l3 will be 15, 45, 12, 34, 32, 80, 42 then print 15, 12, 42.Input FormatFirst line contains the number of elements in l1, n1Next ‘n1’ lines contain the elements of l1Next line contains the number of elements in l2, n2Next ‘n2’ lines contain the elements of l2Output FormatPrint good numbers of l3 one number in a line

4. Describe an algorithm that inserts an integer x in the appropriate position into the list a1,a2, . . . , an of integers that are in increasing order

2. Add Two NumbersMedium29K5.6KCompaniesYou are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list.You may assume the two numbers do not contain any leading zero, except the number 0 itself. Example 1:Input: l1 = [2,4,3], l2 = [5,6,4]Output: [7,0,8]Explanation: 342 + 465 = 807.

Part of an algorithm processes data in two lists: list1 and list2. The algorithm returns a single list: newlist. The size of a list can change as items are added and removed from the list.List operations include:append: adds a new item to a list.len: returns the number of items in a list.The algorithm is shown below:01 function returnlist(list1,list2)02 newlist = []03 index1 = 004 index2 = 005 while index1 < list1.length and index2 < list2.length06 if list1[index1] > list2[index2] then07 newlist.append list2[index2]08 index2 = index2 + 109 elseif list1[index1] < list2[index2] then10 newlist.append list1[index1]11 index1 = index1 + 112 elseif list1[index1] == list2[index2] then13 newlist.append list1[index1]14 newlist.append list2[index2]15 index1 = index1 + 116 index2 = index2 + 117 endif18 if index1 < list1.length Then19 for item = index1 to list1.length20 newlist.append list1[item]21 next item22 elseif index2 < list2.length then23 for item = index2 to list2.length24 newlist.append list2[item]25 next item26 endif27 return newlistState three features of the program that aid maintainability of the code, and outline one additional feature of structured programming that could be used. Describe how the feature would improve maintainablity.
