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, 14, ['i', 'm', '7629', '6869', 'c', 'z', '4147', 'g', '3079', 'L', '8237', '1185', '5877', 'E', 'x', '3539', '4955', '3463', 'c', 'H']
