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: 11, 21, ['1653', 'k', 'E', '8199', 'n', '935', 'I', '9121', 's', '7837', 'F', '1449', '8653', '7205', '411', 'i', 'r', 'o', '8405', '7905', 'y', 'g', '9665']
