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:
1, 6, ['4847', 'W', '283', '1771', '4461', '7905', '1167', 'q', 'Y', '9587', '8979', '1935', 'l', '7099', 'T', 'r', '3255', '1705', 'o', '8363', 'r', 'H', 'Z', '1011', '8449', '3821', 't', '3355', '417']

Ex Output:
790544611771283W4847
