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: 5, 18, ['d', 'T', 'J', 'A', '2999', 'z', '869', 'N', 'e', 'Z', '2177', '6769', '2849', '7473', 'E', '7871', '8213', '4547', '3485', '4537', '5135', '9585']
