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: 10, 16, ['5261', 'e', 'S', 'Q', 'C', '6087', '3535', 'I', '709', '3639', 'w', 'a', '3203', 'D', 'h', '8869', '8315', 'D', 'Y']
Example Output: 8869hD3203aw3639
