[Solved] Identify the error in this code snippet:var list = new LinkedList<int>(); list.AddFirst(1); list.AddLast(2); list.Remove(3); Console.WriteLine(list.Count); | C Sharp (C#)

C Sharp (C#) - Collections

Identify the error in this code snippet:

var list = new LinkedList<int>();
list.AddFirst(1);
list.AddLast(2);
list.Remove(3);
Console.WriteLine(list.Count);

ARemove(3) throws an exception because 3 is not in the list.

BCount property does not exist on LinkedList.

CAddFirst and AddLast methods are invalid for LinkedList.

DRemove(3) does nothing since 3 is not found; Count remains 2.

Step-by-Step Solution

Solution:

Step 1: Understand Remove behavior
Remove(value) tries to remove the first node with that value. If not found, it does nothing and returns false; no exception is thrown.
Step 2: Check Count after removal attempt
Since 3 is not in the list, list remains with 2 elements; Count is 2.
Final Answer:
Remove(3) does nothing since 3 is not found; Count remains 2. -> Option D
Quick Check:
Remove missing value = no error, Count unchanged [OK]

Quick Trick: Remove missing item does not throw error, just returns false. [OK]
