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: 2, 3, ['b', '5615', 'n', '6147', 'W']
Example Output: n5615

Example Input: 7, 7, ['N', '211', 'z', 'H', '709', '5047', 'e', 'o', '2241', 'p', '7679']
Example Output: e
