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.

Ex Input:
7, 12, ['5269', '8059', '6189', '5469', 'D', 'Q', 'C', '8547', 'I', '37', '5495', '6909', 'H', 'H', 'V', '7219', '6235', 'f']

Ex Output:
6909549537I8547C
