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, ['b', 'N', '747', '8835', '3387', '7915', '2093', 'd', 'V', '4285', '8553', '3375', 'D', '4475', '3413', 'W', 'b', 'W', '4867', 'b']
