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, 13, ['9919', '9635', '1935', 'n', '5495', 'R', 'm', 'e', '2751', '7181', 'E', 'p', 'x', 'v', '1373', 'L', '9799', '9357', '5637', '5839', 'a', '7997', 'z', '2555']
