In this task, you are given inputs 'i', 'j', and A, where 'i' and 'j' are integers and A is a list. A list is shown by two brackets and comma-separated numbers and characters inside, like ['1', '12', 'l']. You need to concatenate all elements of A from the ith element to the jth element, and then reverse the resulting 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'. Perform the operations in order, i.e., do not reverse first and then concatenate.

Ex Input:
6, 23, ['a', 't', 'S', '5485', 'n', '5327', '3827', 'v', 'g', 'h', 't', 'y', 'R', 'm', 'y', '2799', 'L', 'T', 'f', '4167', '8589', 'i', '465', 'B', 'd', '6059', '4833']
