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: 8, 19, ['s', 'Z', 'r', 'i', 'A', '1695', 'e', 'F', 'c', '1947', '2041', 'q', '7665', 'y', '911', 'M', '4003', 'X', 'H', 'F', '8999', '1763', 'H', '1453', 'p']
