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: 2, 11, ['p', 'T', 'Z', 'Y', '285', '1191', 'U', '5453', '4243', '9161', 'w', '5191', 'B', '7285', 'D']
Example Output: w161934243545U1911582YZT

Example Input: 5, 5, ['7991', '8029', '9605', 'u', '9539', 'q', '3789', 'i', '8639', '7477']
