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:
6, 7, ['y', '4445', 'k', 'E', '2737', '8341', '1781', 'g', '9877', '1835', 'P', 'i', 'd', 'G', 'j', 'h', 'N', 'L', '2427', 'w', '4785', '8087', '7069', 'A', '7411', '4355', '8529']

Ex Output:
17818341
