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, 19, ['w', 'O', '647', '487', 'y', '4745', 'q', '165', '1481', '2639', '4981', 's', '9801', '1585', 'i', '2339', '1165', 'y', 'D', 'E', '2985', '4277', 'c', '7235', '7239']
