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:
5, 9, ['G', '9679', 'i', 'G', 'N', '7623', 'k', '6063', 'J', 'W', '3613', '8469', '1773', '1741', 'g', '4571', '8803', 'M', 'O', 'l', '6281']

Ex Output:
J6063k7623N
