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: 16, 22, ['S', 'i', '5077', '3433', '7647', '1767', '9271', 'l', '7953', 'l', '8251', 'b', 'N', '3659', '1417', 'e', '4681', 'y', '7705', '9463', '1727', '3943']
