Implement the function create_prefix_lists(list) that will return a sequence of lists, each containing a prefix of list. All the lists should be collected as one big list. For example, for [2, 4, 6, 8, 10] the function should return [[], [2], [2, 4], [2, 4, 6], [2, 4, 6, 8], [2, 4, 6, 8, 10]]. Note: recursion can not be used for this solution, if you are familiar with the concept.

As python is tab specific, you need align the as per the screenshot of the code that I have attached below the code and text version of the code is also provided.

Code:

======

result = []

def create_prefix_lists(lst):

for i in range(len(lst)):

l = []

for j in range(i):

l.append(lst[j])

result.append(l)

result.append(lst)

return result

lis = [2,4,6,8,10]

print create_prefix_lists(lis)

Answer:

See Explaination

Explanation:

code below

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

public class Prefix_test_check {

public static void create_prefix_lists(List elementList) {

if (elementList.size() > 0) {

Collections.sort(elementList);

List newArrayList = new ArrayList();

newArrayList.add("[");

System.out.print(newArrayList);

System.out.print(",");

newArrayList.clear();

int counterDataObj = 0;

for (int iObjectData = 0; iObjectData < elementList.size(); iObjectData++) {

newArrayList.add(elementList.get(iObjectData));

counterDataObj++;

if (counterDataObj == elementList.size()) {

System.out.print(newArrayList);

System.out.print("]");

} else {

System.out.print(newArrayList);

if (counterDataObj != elementList.size()) {

System.out.print(",");

}

} else {

List emptyDataList = new ArrayList();

emptyDataList.add("]");

System.out.print(emptyDataList);

}

public static void main(String args[]) {

List elementList = new ArrayList();

elementList.add(2);

elementList.add(4);

elementList.add(6);

elementList.add(8);

elementList.add(10);

create_prefix_lists(elementList);

}
