In the previous update both the lists when: i. key 17 is deleted ii. a new integer 26 is inserted in the end of the 2nd list

To answer the question, we need to understand that we are dealing with two operations on two lists:

1. Deleting the key 17 from the first list.
2. Inserting a new integer 26 at the end of the second list.

Let's assume we have two lists as follows:

List 1: [3, 17, 4, 12, 5] List 2: [1, 9, 17, 8, 15]

We will perform the operations step by step.

Step 1: Deleting key 17 from the first list

To delete an element from a list, we need to find the element first and then remove it. Here's how you can do it in Python:

list1 = [3, 17, 4, 12, 5]

# Check if 17 is in the list
if 17 in list1:
    list1.remove(17)  # Remove the element 17

print(list1)  # Output will be [3, 4, 12, 5]

After the deletion, List 1 will look like this:

Index	0	1	2	3
Value	3	4	12	5

Step 2: Inserting a new integer 26 at the end of the second list

To insert a new element at the end of a list, you can use the append() method in Python:

list2 = [1, 9, 17, 8, 15]

# Append 26 to the end of the list
list2.append(26)

print(list2)  # Output will be [1, 9, 17, 8, 15, 26]

After the insertion, List 2 will look like this:

Index	0	1	2	3	4	5
Value	1	9	17	8	15	26

Summary of Operations

Here's a summary of the changes made to both lists:

Operation	List 1 Before	List 1 After	List 2 Before	List 2 After
Delete 17	[3, 17, 4, 12, 5]	[3, 4, 12, 5]	[1, 9, 17, 8, 15]	[1, 9, 17, 8, 15]
Insert 26	[3, 17, 4, 12, 5]	[3, 4, 12, 5]	[1, 9, 17, 8, 15]	[1, 9, 17, 8, 15, 26]

Conclusion

After performing the operations, we have successfully deleted the key 17 from the first list and inserted the integer 26 at the end of the second list. The lists are now modified as shown in the summary table above.
