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:
7, 15, ['t', '8459', 'T', '7029', '3995', '8369', 'H', 'o', '8539', '9399', 'C', '6335', '1161', 'F', 'N', 'Y', 'Y', 'G', 'R', '3577', '4897', 'r', 'j', '9077', 'u', '4969', 'Z', '8933']

Ex Output:
