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, 5, ['5837', 'M', 'H', '4703', 'K', 'k', 'P', 'f', '2471', '9617', '453', '9105', 'w']
Example Output: K4703
