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, 6, ['Q', 'C', '3939', '5659', '6505', '2527', '2785', 'H', '2359', '925', '921', 'f', '1597', '7131', 'B', '3075', '9017', 'T', '8723', '2717']
Example Output: 252765055659
