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: 3, 12, ['J', '9903', 'z', 'm', 'S', 'r', 'f', '2291', '6021', 'S', '4889', '7405', 'n', 'R', 'k', '8303', 'J', 'l', 'U', '4911', '4327', '211', 'F', '5401', 'y', '865']
