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: 6, 20, ['d', '9727', '9597', 'a', '5529', 'f', '245', '363', '593', '3005', 'Z', '2535', 'r', 'x', 'e', 'A', '571', 'E', 'G', '6585', 'X', 'A', 'g', 'b', 'm', '3437', 'o', '4019']
