Java实现复杂链表的复制

过程很简单，直接上代码

import java.util.HashMap;
import java.util.Map;

public class Solution {
	
	
    public RandomListNode Clone(RandomListNode pHead) {
    	
    	Map map = new HashMap();
    	RandomListNode currentNode = pHead;

    	// 复制节点中的属性
    	while (currentNode != null) {
    		map.put(currentNode, new RandomListNode(currentNode.label));
    		currentNode = currentNode.next;
    	}
    	
    	
    	// 复制节点中的关系
    	currentNode = pHead;
    	while (currentNode != null) {
    		map.get(currentNode).next = map.get(currentNode.next);
    		map.get(currentNode).random = map.get(currentNode.random);
    		currentNode = currentNode.next;
    	}
    	
    	return map.get(pHead);
        
    }
}
