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.

Example Input: 16, 17, ['5473', '5513', 'G', '2465', '1513', 'Z', '5341', 'X', 'R', '4355', '3215', 'W', 'k', 'C', '9845', '5377', 'c', '3169', '7049', '9795', 'R', '7301', 'C', 'm', '983', '2997', 'I']
