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, 8, ['l', 'D', '9033', '4155', '9215', '4615', '5411', 'x', '6533', 'z', 'p', 'm', '6559', '6803', 'p', 'm', '4681', 'b', '6531', 's', '8711', '1385', 'A', 'U', 'b']

Ex Output:
x5411
