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:
3, 4, ['109', 'U', '6833', '6807', '4937', '7119', 'q', 'V', '5647', 'H', 'A', 'Y', 's', '3723']

Ex Output:
