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: 11, 12, ['4937', 'd', '3503', 'G', '4955', 'W', '1039', 'G', 'o', '5571', '6755', '9215', 'R', '8897', 'M', '4335', 'B', '3991', '9037', 'm', '2171', '9675', '6963']
