In this task, you are given inputs i,j, and A, where i and j are integers and A is a list. You need to concatenate all elements of A from the ith element to the jth element, and print the resultant string. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j.

Example Input: 14, 18, ['v', '6023', '2467', '8911', '1449', '4251', 'L', 'E', '8575', 'J', 't', '1571', '631', 't', '7285', 'n', '3601', '3457', 'T', 'i', 'F', '6671', '5771', '897', '579', '3859', 't', '263', '8253']
