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.

Example Input: 16, 24, ['w', 'K', 'd', 'm', '7173', 'Q', 'D', 'h', 's', 'O', '9497', 'L', 'O', 'G', 'T', 'F', '2749', '6165', '8807', '3025', 'a', '953', '5531', 'P', '3635', '1789', 'u', '7785', '5287']
