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.

Example Input: 8, 10, ['A', 'C', '6441', '275', 'O', 'v', '5787', 'E', 'h', '6821', 'x', '2819', 'N', '3909']
Example Output: 6821hE

Example 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']
Example Output: 1261

Example Input: 13, 21, ['s', 'h', '8999', 'w', 'V', 's', 'y', 'U', 'o', '3869', 'm', '2607', '8657', 'J', 'L', '7335', 'K', '2655', 'R', 'T', 'o', 'v', 'g', '8081', '3655', 'a']
Example Output:
