In this task, you are given inputs i, j, and A, where i and j are integers and A is a list. You need to find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output the resultant 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 concatenate the elements and then reverse the string.

Example Input: 24, 30, ['e', 'n', '9415', '6975', '3185', '5191', '2907', 'E', '6901', 'Y', 'w', '2493', 'l', 'A', 'n', 'M', 'J', 'h', '1061', 'J', '8595', 'm', 'j', '9115', 'l', '2641', '4883', '3453', '841', '3985']
Example Output: 3985841345348832641l9115
