Definition: 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.
Input: 12, 15, ['d', '1163', 'i', 'V', '799', 'U', 'z', '2175', '7889', '2337', '1617', '7723', 'F', '8637', '7527', '4215', '2787', '4495', 'E', '57', 'b', 'l', '9363', '2383', 'v', 'S', '1235', 'x', '191', 'J']
