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, 10, ['a', '2185', '9875', 'Y', 'j', 'A', 'D', 'w', '9467', '3199', '6347', '9853', 'U', 'H', '3471', '6223', '5279', 'D', 'g']
