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: 3, 12, ['2159', 'f', 'u', '2675', '7357', '9325', '1275', '8897', 'I', '2095', '5835', '577', 'g', '2783', '7843', '8517', '4185', '5847', '2645', '2357', 'l', 'v', '2239', '141', 'o', '2529', '7977', '8445', '2363']
