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, 16, ['4917', 'L', '6299', '1183', '323', '7973', '4675', 'j', '227', '4893', '1923', 'R', '6713', '6793', '6337', 'k', '5361', '5145', '1171', '9159', 'B', 'H', '593', 'p', 'E', '4315', 'n', '2469', '3461']
