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:
15, 29, ['w', '5845', '5777', 'V', '7279', '3285', '4985', 'v', 'A', '2911', 'J', 'w', 'f', 'Z', '5657', '9001', '1447', '4845', '2561', '7819', '33', 'F', 'y', '3849', 'S', '8987', 'U', '7975', '1775', 'x']
