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: 1, 7, ['k', '5831', '5123', '2685', '9917', 'V', 'e', 'S', 'x', 'U', '7117', '8251', 'p', 'Q', 'Q', '1871', 'V', 'E', 'b', 'L', 'a', '693', '8297', 'r', 'y', 'U', '9771', 'r', 'x', 'W']

SOLUTION: k, S, Q, 693, x

PROBLEM: 1, 1, ['S', 'g', 'r']

SOLUTION: S, g, r

PROBLEM: 1, 3, ['g', '5347', 'H', '1875', '8583', '1939']

SOLUTION:
g, 1875
