TASK DEFINITION: In this task, you are given inputs k, i, and A, where k and i are integers and A is a list. You need to find every ith element of A starting from the kth element. The process stops when the position of the next ith element exceeds the length of the list.
PROBLEM: 4, 4, ['k', 'K', 'D', 'r', 'U', '4631', '1245', 'E', '617', '4359', '5281', 'p', '5051', '4825', 'Y', '9983', '2505', 'e', '5659', '3295', '8633', 'o', '983', '6303', '5165', 'u', 'f', 'i', '4615']

SOLUTION: r, E, p, 9983, 3295, 6303, i

PROBLEM: 1, 1, ['H', '5297', 'H']

SOLUTION: H, 5297, H

PROBLEM: 2, 1, ['C', '6321', '2509', '4775', 'G', '5133', 'p', '9501', 'C', '223', 'd', 'B', '6051']

SOLUTION:
6321, 2509, 4775, G, 5133, p, 9501, C, 223, d, B, 6051
