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: 6, 16, ['W', '5585', '5039', 'a', '7345', '7175', 'j', '943', '5895', '9175', 'N', '4835', 'v', '3609', '3557', 'b', '1581', 'n', 'i', '8403', 'S', 'N', 'z', '87', 'o']
