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, 23, ['Q', 'V', 'M', '8999', 'n', 'o', '5937', 'P', 'w', '695', 't', '8305', 't', '1757', 'z', '3051', 'y', 'r', 'p', '3361', '3675', '4019', 'n']
