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:
7, 12, ['R', '3623', 'M', '5183', '1901', '7279', 'w', 'L', '2779', '6019', 'Q', '1393', '1989', 'h', 'Q', 'I', '915', '4425']

Ex Output:
