Write a method called rotate that moves the value at the front of a list of integers to the end of the list. For example, if a v

ariable called list stores the values [8, 23, 19, 7, 45, 98, 102, 4], then the call of list.rotate(); should move the value 8 from the front of the list to the back of the list, changing the list to store [23, 19, 7, 45, 98, 102, 4, 8]. If the method is called for a list of 0 elements or 1 element, it should have no effect on the list. You may neither construct any new nodes to solve this problem nor change any of the data values stored in the nodes. You must solve the problem by rearranging the links of the list.
