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.

Answer:

Explanation:

public void rotate()

{

if(front == null)

return;

ListNode current = front;

ListNode firstNode = current;

while(current.next != null)

{

current = current.next;

}

current.next = front;

front = firstNode.next;

firstNode.next = null;

}

Assume that you have an array of integers named arr. The following program segment is intended to sum arr [0]through arr[n−1], w
Paladinen [302]

Answer:

There is only one modification in the above loop i.e. while loop should be like this--

while (i != n)

     {

         sum+=arr[i];   // Line 1, In question segment it is line 2.

          i++;                // Line 2,  In question segment it is line 1.

     }

Output:

Now if the array input is 1,2,3,4,5 then the output is 15.

Explanation:

In the above question, all the line of the segment is right except the body of the loop because--

  • The First line of the loop is increment statement which increments the value of "i" variable from 1 and the value of "i" variable will be 1 in the first iteration of the loop
  • The second line starts to add the value from 1'st index position of the array. Hence the segment gives the wrong answer. It adds the arr[1] to arr[n-1].
  • So I interchanged both lines of the while loop as shown in the answer part. I make the line 1 (In question segment) as line 2(In answer part) and line 2 (In question segment) as line 1 (In answer part).

Now It gives the correct output because it can add arr[0] to arr[n-1].
