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: 12, 13, ['x', 'V', '4453', 'Q', 'r', 'p', 'M', '2321', 'Q', '9461', 'h', 'e', 'D', 'F', 'o', 'd', 'G', 'A', 'A', 's', '2777', '3963', '3363', 'C', 'X', 't']
Example Output: De
