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: 17, 21, ['3911', '3419', '2079', '483', '4525', 'b', '1111', '2005', 'o', 'J', '7361', 'h', '1027', 'B', '1731', '1797', '1317', '6915', '5979', '6261', '4221', 'D', '6225', '3079', '9765']
