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, 15, ['L', 'O', '2407', 'W', '2159', 'P', 'c', 'E', '1431', 'y', '5833', '1289', '8625', 'S', '6873', 'C', '431', 'F', '5261', 'b', '8783', 'H', '4147', '7071']
