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.

Ex Input:
11, 22, ['419', '1533', 'E', 'v', 'S', 'W', '3961', '1175', 'W', 'N', 'F', '1771', '2317', 'y', '3733', 'i', 'S', '5335', '349', '9817', 'F', 'O', '7137', 'X', '6001']
