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.

Input: Consider Input: 4, 19, ['I', 'h', 'D', 'd', 'e', 'X', 'h', '2821', 'y', '2537', '2345', 't', 'I', 'i', 'D', '543', '2469', 'j', 'V', 'U', '8523', '605', 'J', '6675', '8559', 'n']
