• While (temp != null)
• {
• Count += temp.info;
• Temp = temp.next;
• }
• Return count;
• }
• B) public int countIt(Node temp) {
• While (temp != null)
• {
• Count++;
• }
• Return count;
• }
• C) public int countIt(Node temp) {
• While (count != null)
• {
• Count++;
• Temp = temp.next;
• }
• Return count;
• }
• D) public int countIt(Node temp) {
• While (temp != head)
• {
• Count++;
• Temp = temp.next;
• }
• Return count;
• }
• E) public int countIt(Node temp) {
• While (temp != null)
• {
• If (next != null) count++;
• Temp = temp.next;
