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: 15, 18, ['1581', 'Y', '6213', '8665', '9709', '7741', '585', '2989', '5307', 'Q', '8567', '201', '9457', '8277', '3339', 't', 'b', '5373']
