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: 4, 10, ['4619', '1689', '1987', '9711', 'K', 'a', '9193', 'y', 'c', 'O', 'u', 'h', 'v', 'o', '927', '2323', 'Z', '5115']
Example Output: Ocy9193aK9711
