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.

Ex Input:
9, 14, ['X', '2369', '2305', '2247', '3667', 'j', 'm', '7097', '115', '3757', 'g', '6065', '4021', '2241', 'v', '7439', 'G', 'H', '6543', 'p', 'Y', 'X', 'S', 'i', 'b', '2483', '5915']

Ex Output:
224140216065g3757115
