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, 23, ['n', 'P', 'w', 'i', 'M', '7085', '7223', 'K', '5629', '5313', '9025', 'X', '25', '1393', '3911', 'C', 'O', '3551', '4245', 'G', 'A', '4305', '1309', '4079', '3605', '8637', '4917', '4995', '4501', '3639']
