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, ['q', 'g', '1455', 'f', '2605', 'B', 'r', 'B', 'y', 'z', '8295', '7259', '4945', '4519', '7885']

Ex Output:
yBrB2605
