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:
8, 12, ['L', 'M', '3799', '5741', 'U', 'a', 'g', '9643', 'i', 'u', 'i', '9355']

Ex Output:
9355iui9643
