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, 22, ['e', 'P', 'A', 'k', 'r', '8249', 'A', 'E', 'h', '3091', '4661', 'I', 'T', 'G', '2959', '3103', 'Y', '8669', 'y', 'k', 'N', 'h', '9367', '3831', '9823']
