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, ['5593', 'C', '4497', 'Q', '6339', '4147', '4209', 'S', 'Y', '1523', '6577', 'I', 'a', 'z', 'T', 'R', '5257', '4293', 'f', '5075', '2101', 'Z', '5595']
