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: 7, 16, ['a', 'V', '5823', 'd', '7799', '9435', '2737', 'x', '3463', '9505', '2549', '3379', 'k', 'W', 'l', '4717', '5319', 'Y']
