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: 3, 16, ['3715', '1331', 'A', '5257', '2749', '1769', 'b', '4439', 'Y', '7483', '2453', '5475', '1939', '1219', 'I', 'T', '6447', 'k']
