Definition: 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.
Input: 17, 28, ['s', 'V', '7851', 'W', 'X', '7247', '135', 'V', 'B', '2693', 'g', '5661', '5509', 'y', '2507', 'e', 'X', 'E', '9753', '517', 'n', '5701', '3837', '9847', 'u', 'W', 'Z', 'P', 'D', 'b']
