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: 14, 23, ['i', '6385', 'a', 'M', 'B', 'Q', '8929', 'N', 'z', '8359', '5095', 'c', 'Z', '4689', 'p', 's', '5489', '1097', '591', '2837', '8299', '6039', '1819', 'O', '7723']
