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: 13, 14, ['B', 'e', '1943', 'u', 'b', 'E', '4089', 'y', 'x', 'T', 'M', 'P', 'a', '2485', 'R', '9725', 'y', '8137', 'F', 'g', '8713', '9329', '5559', '4243', '5865', '2619', '9789', 'p', '7217']
