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:
9, 16, ['h', '9775', 'a', '8833', '5813', '7225', 'o', 'i', 'i', '6747', '521', '8947', '2191', 'h', 'v', '8275']

Ex Output:
