Question

Write a program in ADA that should be able to read two lists and produce as output the shuffle of two lists (all shuffledlists): You type [a,b,c] [1,2,3] and as output you will obtain [a,b,c,1,2,3]; [a,b,1,c,2,3]; .... [1,2,3,a,b,c] The representation of list would be your choice (arrays or linked lists)

Answer 1

we can have a problem in which we need to perform shuffle operation in list. This task is easy and there are straightforward functionalities available in Python to perform this. But sometimes, we need to shuffle two lists so that their shuffle orders are consistent. Let’s discuss a way in which this task can be performed.

Method : Using zip() + shuffle() + * operator
In this method, this task is performed in three steps. Firstly, the lists are zipped together using zip(). Next step is to perform shuffle using inbuilt shuffle() and last step is to unzip the lists to separate lists using * operator.

import random

# initializing lists

test_list1 = [6, 4, 8, 9, 10]

test_list2 = [1, 2, 3, 4, 5]

# printing lists

print("The original list 1 : " + str(test_list1))

print("The original list 2 : " + str(test_list2))

# Shuffle two lists with same order

# Using zip() + * operator + shuffle()

temp = list(zip(test_list1, test_list2))

random.shuffle(temp)

res1, res2 = zip(*temp)

# Printing result

print("List 1 after shuffle : " + str(list(res1)))

print("List 2 after shuffle : " + str(list(res2)))

Output :

The original list 1 : [6, 4, 8, 9, 10] The original list 2 : [1, 2, 3, 4, 5] List 1 after shuffle : [6, 10, 4, 8, 9] List 2 after shuffle : [1, 5, 2, 3, 4]
