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: 12, 17, ['2529', 'U', 'd', '9709', 'm', '2735', '5283', 'c', 'Q', 'E', '5785', '5913', 'k', 'K', 'i', 'V', '6369', '7167', 'B', '263', 'D', '8379', 'P', 'C', '4795', 'n', '1993', '1587', '6929', '4739']
Example Output: 6369ViKk5913
