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, 8, ['6403', 'T', '2925', 'k', 'd', '5945', 'Q', '8379', 'R', '5991', '6583', '7577', 'V', 'Q', '5317', 'K', '7367', '5663', 'e', '1603', '8359', 'J', 'B', '3967']

Ex Output:
8379Q
