数据结构实验之链表五:单链表的拆分
TimeLimit: 1000MS Memory Limit: 65536KB
ProblemDescription
输入N个整数顺序建立一个单链表,将该单链表拆分成两个子链表,第一个子链表存放了所有的偶数,第二个子链表存放了所有的奇数。两个子链表中数据的相对次序与原链表一致。
Input
第一行输入整数N;;
第二行依次输入N个整数。
Output
第一行分别输出偶数链表与奇数链表的元素个数;
第二行依次输出偶数子链表的所有数据;
第三行依次输出奇数子链表的所有数据。
ExampleInput
10
1 3 22 8 15 999 9 44 6 1001
ExampleOutput
4 6
22 8 44 6
1 3 15 999 9 1001
Hint
不得使用数组!
