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, 10, ['3359', 'Q', 'J', '8995', '8963', 'k', '7331', 'C', '4361', 'z', 'O', 'f', 'g', 'Y', 'Y', '3685', '5475']

Ex Output:
z4361
