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: 19, 25, ['l', 'i', 'v', '2813', '4893', '3263', 'a', 'H', 'H', 'c', 'w', '91', 'X', '8227', '917', 'D', '4803', 'T', 'v', '9273', '9365', 'z', 't', 'b', '2077', '1641', 'J', '7745']
Example Output: 2077btz93659273v
