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.

Example Input: 9, 21, ['d', 'K', '4747', 'J', '5273', 'R', '5449', '6823', '2003', 'M', '3201', 'D', '5025', '5151', 't', '5203', '1073', 'E', 'O', 'M', 'R', '3039', '4781', 'b', '6819', '4025', '9125', '3733', 'x']
