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: 7, 14, ['R', 'F', 'i', '3355', '4543', 'E', 'j', 'q', 'B', 'F', '7195', 'B', '2255', '7513', '5549', '1389', '9069', 'U', 'v']
Example Output: 75132255B7195FBqj
