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: 14, 24, ['1159', '4039', '5717', 'b', 'S', '5827', 'A', 'F', '4441', 'q', '4443', '8147', 'T', '7809', '2349', 'L', '6887', 'X', '9193', '943', '9187', '1005', 'U', '2991', '7433']
