Teacher: In this task, you are given inputs i and A, where i is an integer and A is a list. You need to list all the elements of A preceding the last i elements. i will always have a value less than the length of A.
Teacher: Now, understand the problem? If you are still confused, see the following example:
3, ['a', '34', 'f', '931', '7', '3432', '13245', '762']
Solution: a, 34, f, 931, 7
Reason: Here, all the elements except the last 3 from the list are 'a', '34', 'f', '931', and '7'.

Now, solve this instance: 1, ['4721', 'Y', '8579', 'k']
Student:
4721, Y, 8579
