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: 18, 25, ['t', '5461', 'k', '9239', 'x', 'A', 'e', '447', '9565', '5455', '6397', '2405', 'b', '691', '3977', '519', '1507', 'B', '2051', 'k', 'E', 'M', '1955', '1441', '6303', 'N']
