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: 2, 7, ['j', '7173', 'D', '6745', '9469', '3259', '5885', '9507', 'U', '8735', 'C', 'O', '2055', 'm', '2265', '9445', '6445']
Example Output: 5885325994696745D7173

Example Input: 11, 11, ['2369', 'J', '5461', '5037', 'L', '3003', 'K', 'g', '5417', 'Q', '3309']
Example Output: 3309

Example Input: 3, 3, ['8855', '6889', 'D', '2197']
