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, 19, ['6221', 'c', 's', '9789', 'P', '507', '8463', 'v', '4431', 'B', 'S', 'g', '3033', 'n', 'P', 'L', 'a', 'P', 'i', 'K', 'A', 'i', '4109', '9415', 'z', 'n']
