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, 17, ['g', 'r', '5649', '939', 'z', 'm', '5247', '2575', 'i', 'P', 'A', 'b', 'Y', '8519', '8345', 'J', 'a', '4853', '8683', 'u', '5575', 'Z', '2423']
