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, 24, ['5619', 'w', 'P', 'Q', 'i', 'm', '5793', 'n', '3491', '4755', 'u', '5093', '1049', 'Y', '9741', '465', 'r', 'K', 'B', '9675', '7939', '6905', '3563', '8849', 'x', '7421', '1285']
