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:
4, 8, ['3807', '5231', '8743', '3165', 'B', 'h', 'V', '6185', '8317', '8533', 'j']

Ex Output:
6185VhB3165
