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: 6, 15, ['T', 'u', 'v', '5523', '3025', 'P', '2843', '5033', '3237', 'X', 'e', '5147', '849', '9773', '7559', 's', 'L', 'y', '6195', '5073', 't']
