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:
22, 22, ['D', 'U', 'O', '2609', '7785', 'F', 'v', 'g', '5451', 'W', 'D', 'n', 'R', '1483', 'o', 't', '6741', 's', 'u', '9611', 'Y', '1261', '8023']

Ex Output:
1261
