Definition: 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.
Input: 10, 30, ['B', 'b', '5053', 's', '2761', '8159', '7487', '4645', '911', 'S', '3505', 'n', 'G', 'Q', '6745', 'w', '9169', 'n', '6815', 'R', 'f', '917', 'f', '2361', 'b', '1985', '6167', 'Y', '3193', '1149']
