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, 7, ['a', '9461', '851', '2443', 'l', '9851', 'V', '3091', '3339', '2931', '4273', 'U', 'H', 'L', '7779', 'e', '5295']

Ex Output:
V
