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: 12, 18, ['4317', '6601', 'Q', 'I', '7383', '4399', 'O', 'f', 'l', '1017', 'k', '4883', 'r', '5967', '4801', 'r', 'r', 'd', 'm', 'E', '8403', '979', '2463', '4221', '2659']
