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:
8, 9, ['4949', '5903', 'o', 'B', '4919', '7465', 'w', '4661', 'E', '6861', '9491', 'D', 'K']

Ex Output:
E4661
