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, 16, ['3661', '8985', 'X', '193', '3329', 'B', '843', 'r', '8273', '9019', '5771', '7523', 'U', 'i', '2029', '4953', '3071', 'Z']
Example Output: 35949202i
