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, 27, ['A', '7769', '4011', 'c', '7483', 't', '583', '5847', '8957', 'i', 'v', 's', '2195', '5211', 'p', 'C', 'G', 'K', '6607', 'm', '7253', 'x', '3363', '5015', 'q', '1613', 'l', '7331', '6945']
