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.
One example: 3, ['a', '34', 'f', '931', '7', '3432', '13245', '762']
Solution is here: a, 34, f, 931, 7
Explanation: Here, all the elements except the last 3 from the list are 'a', '34', 'f', '931', and '7'.

Now, solve this: 6, ['C', '7497', '6549', '2901', 'f', 'k', '305', '4409', '9883', 'H', '1293', '2461', '6915', 'M', '8585', '7563', '2815', 'Y', '4909', '8041', 'X', 'n']
Solution:
C, 7497, 6549, 2901, f, k, 305, 4409, 9883, H, 1293, 2461, 6915, M, 8585, 7563
