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: 1, 30, ['u', '2967', '8693', '6963', 'w', 'A', '1211', '2737', '3565', 'i', '3755', 'N', 'y', '7541', '685', '1191', '1837', '7215', '7191', '515', 'm', 'b', 'm', 'E', 'j', '5337', '7119', '599', '5097', '3399']
