題目

給定兩個有序連結串列的頭指標head1和head2，列印兩個連結串列的公共部分。

程式碼實現

public class PrintCommonPart {
    public class Node {
        public int value;
        public Node next;

        public Node (int data) {
            this.value = data;
        }
    }

    public void printCommonPart (Node head1,
 
 Node head2) {
        System.out.println("Common Part: ");
        while (head1 != null && head2 != null) {
            if (head1.value < head2.value) {
                head1 = head1.next;
            } else if (head1.value > head2.value) {
                head2 = head2.next;
            }
 
 else {
                System.out.println(head1.value + ' ');
                head1 = head1.next;
                head2 = head2.next;
            }
        }
        System.out.println();
    }
}
