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: 1, 2, ['o', 'b', '7511', 'Z']
Example Output: bo

Example Input: 6, 9, ['3523', '1127', '1027', '1757', '7871', 'p', '809', '7035', 'H']
Example Output: H7035809p

Example Input: 2, 13, ['1185', 'b', 't', '3753', '5269', '6693', 'H', 'D', 'p', '3185', '8459', 'K', '693', '7013', 'n', 'Y']
Example Output:
