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, 16, ['F', 'l', 'Q', 'l', 'N', 'c', '9969', '4953', '8673', '7567', '7045', '2257', '2163', 'Y', 'X', '155', 'S', '771', '5885', '8401', '5999', '341', 'v']
