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.

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

Output: 6821hE
