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: 18, 22, ['S', '9355', '4473', '75', '4341', 'c', 'L', 'H', '2053', '4235', 'e', 'g', 'V', '4015', 'V', '517', '6753', 'x', '2991', 's', 'w', 'o', '6397']
Example Output: ows2991x
