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.

Example Input: 2, 14, ['8337', 'z', '7487', 'j', 'g', 'e', 'i', 'm', 'b', 'a', '9981', '3093', 'Y', 'S', '5409', 'F', 'V']
