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: 1, 15, ['y', 'M', '4905', 'O', '5281', 's', '6021', '4001', '699', 't', '6701', 'n', 'o', 'o', '8605', 'R', '3793', 'i', 'z', 'x', 'p', '7095', '3565', '3365', 'a', '8719', '8517']
