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: 12, 16, ['u', '551', 'L', 'g', 'd', '2453', 'J', 'f', '8211', 'L', '241', 'l', 'G', 'F', '9043', 'f', '3977', 'P', '4371', '7687', 'A', '8181', '5251', 't', '6837']
Example Output: f9043FGl
