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: 12, 14, ['G', '551', '923', '6749', 'y', '7973', 'S', 'N', '3221', '3109', '2345', '393', 'c', '8071', 'v', 'h', 't', 'C', '1577', '4799', 'S', 'i']
