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: 9, 18, ['K', 'z', 'N', 'M', 'C', '4085', 'Y', 'T', 'J', 'T', 'B', '1671', '1083', '2961', 'T', 'b', '5905', 'U', '6817', 'K', '9291', 'O']
Example Output: U5905bT296110831671BTJ
