Question 446
Remove the First Node Holding a Value
Remove the First Node Holding a Value
Unlike a counted walk, this one stops on data you cannot predict, so carry two cursors: previous stays one node behind current, because the link you must rewire lives in previous.
Requirements:
1. remove(int value) unlinks the FIRST node holding value and returns true.
2. It returns false when no node holds value, including on an empty list.
3. A match on the head node is its own branch - there is no previous node to rewire.
The Node class is provided - do not rename it and do not add public to it, because a Java source file may contain only one public class.
Do NOT write a main method.Expected Output:
true 10 -> 30 -> 20 -> null true true 10 -> 30 -> null false
= newline. The output ends with a newline — print one after the last line.
