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, ['6505', 'z', '6017', 'y', '6807', 'B', 'A', 'R', 'Q', 'O', '5737', '967', '183', 'i', 'q', '2933', '9227', '8783', '9135', '5209']
