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: 6, 11, ['F', '8903', 'h', 'n', 'A', 'i', 'l', 'w', '4403', '633', '9105', '8597', '5207', '4435', 'N', 'x', '7105', 't', '9959', '2535', '7423', '9669', 'e']
