Definition: 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: 2, 15, ['a', 'b', 'v', '6895', 'C', '5927', 'u', '2775', '1009', 'D', '4029', 'l', 'r', '4337', '4411', 'n', 'J']
