Question
Write a Python program to interchange the first and last element of the ListConstraints:Input Format:Line 1: <Read a List>Output Format:<List>Example:Input:[5,10,15,20,25,30,35,40]Output:[40, 10, 15, 20, 25, 30, 35, 5]Explanation:NAPublic Test Cases:# INPUT EXPECTED OUTPUT1 [5,10,15,20,25,30,35,40][40, 10, 15, 20, 25, 30, 35, 5]Run CodeSubmit Code12345l1=eval(input())l1=[int(x) for x in l1]if l1: l1[0],l1[-1]=l1[-1],l1[0]print(l1)OutputCustom Input
Solution
Sure, here is a Python program that interchanges the first and last element of a list:
# Read a list from user input
list1 = eval(input())
# Check if the list is not empty
if list1:
# Swap the first and last elements of the list
list1[0], list1[-1] = list1[-1], list1[0]
# Print the modified list
print(list1)
You can run this program and input a list like [5,10,15,20,25,30,35,40]. The output will be [40, 10, 15, 20, 25, 30, 35, 5], which is the original list with the first and last elements swapped.

Alternate Elements in Linked ListYou are now well versed with the concepts of Linked Lists. So, now you have been given an advance coding challenge, i.e., you have to create the code on the topic linked lists such that it will give the output of only elements in alternate position from last to first and then first to last. Constraints:Input Format :First line of input contains the number of integers.Next lines are followed by the integer values.Output Format :Corresponding output.Example:Input 1:51 2 3 4 5Output 1:1 3 55 3 1 Input 2:411 12 14 13Output 2:12 1313 12 Explanation:Alternate elements from first element are 1 3 5Alternate elements from last to first are 5 3 1Public Test Cases:# INPUT EXPECTED OUTPUT1 51 2 3 4 51 3 5 5 3 1 2 4 11 12 14 1311 14 13 12
