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: 18, 18, ['3693', '9371', 'o', 'o', '3695', '4107', '2179', '9691', 'w', 'A', '2597', '5473', '9583', '3699', 'k', 'k', '4921', '8101', '4261', 'B', 'Y', 'U', '8351', 'E', '5317']
