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:
11, 18, ['o', '2733', '4621', 'X', 'Y', 'T', '6999', '1665', 'F', '351', '3567', '7331', 'w', 'S', 'c', '9593', '6431', '735', '8743', 'Q', 'p', '569', '6991', '6087', '2659', '2909', '6083', 'd']

Ex Output:
