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:
2, 8, ['613', 'z', '4591', 'p', 'e', '8373', '689', '5073', 'p', '7943', '3161', '2481', 'j', 'v', '9863', 'G', '8923', 'S', 'm', 's', '543', '3225', '7617', 'c', '7615', '3219', 'x', 'C', 'f']

Ex Output:
