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, 16, ['9149', '957', 'O', '253', '3863', '1621', 'n', '9675', '4259', '7973', '193', '4731', '453', '9153', 'w', 'h', 'Y', '6983', 'z', '5259', 'u', '6641', '6749', 'v', '3315', 'P', '6949', '2725', '7697', 'C']
