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, 25, ['3887', 'X', '31', 'p', '29', '2267', '5367', 'P', '4071', '4409', '3501', '9915', '7933', '5203', 'C', 'V', '1605', '573', '951', '9233', '8211', 'l', 'F', '4309', 'w']
