C 言語の反復メソッドを使用して、リンク リストの最後の k ノードを逆順に出力します。

Linked List: 29->34->43->56->88
Input: 2
Output: 56 88

START
   Step 1 -> create node variable of type structure
      Declare int data
      Declare pointer of type node using *next
   Step 2 -> create struct node* intoList(int data)
      Create newnode using malloc
      Set newnode->data = data
      newnode->next = NULL
      return newnode
   step 3 -> Declare function void rev(struct node* head,int count, int k)
      create struct node* temp1 = head
      Loop While(temp1 != NULL)
         count++
         temp1 = temp1->next
      end
      Declare int array[count], temp2 = count,i
      Set temp1 = head
      Loop While(temp1 != NULL)
         Set array[--temp2] = temp1->data
         Set temp1 = temp1->next
      End
      Loop For i = 0 and i < k and i++
         Print array[i]
      End
   Step 4 -> In Main()
      Create list using struct node* head = intoList(9)
      Set k=3 and count=0
      Call rev(head,count,k)
