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: 19, 26, ['4699', 'J', 'o', '7127', 'A', 'r', 't', '2571', 'Z', 'A', 'i', 'V', '2275', '3277', 'T', 'C', 'k', '975', '5591', '4205', '9873', '141', '9775', 'w', '111', '2585', '8751', '2173']
