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: 19, 24, ['D', 'q', 'u', 'a', 'G', '1659', 'H', '5289', 'n', '9491', '3407', 'K', 'u', 'X', 'a', 'Q', '8471', '6927', 'H', 'R', 'o', '4317', 'p', '4387', '2419', 'b', 'F']
