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: 5, 5, ['M', 'N', 'S', '1125', 'B']
Example Output: B

Example Input: 9, 11, ['L', 'L', '9477', 'a', 'H', 'O', '2765', 'O', 'n', 'Y', '9271', '9751', '7425', 'g', '683', '1849', 'V', 'z', 'b', '1187', 'L', '7325', '3743']
Example Output: 9271Yn

Example Input: 3, 5, ['N', '2967', '5757', 'b', 'j', '2161', '453', '6795', 'i']
Example Output:
