输出格式完全按照题目要求输出，运行后提示结果出错。出错原因未知。先贴上代码以后再DEBUG－＝

答题说明:

#include <stdio.h>
#include <stdlib.h>
typedef long long FINGER;

FINGER getReturn(){
	char buffer[12];
	char temp = 0;
	for(int i = 0;i < 10;i++){
		temp = getchar();
		if(temp == '\n'){
			return atoi(buffer);
		}
		buffer[i] = temp;
	}
	return 0;
}

typedef struct _FINGERRECORD{  
    FINGER data;  
    struct _FINGERRECORD *next;
} FINGERRECORD; 

int where(FINGER input){
	if(input >= 1 && input <= 5)
	{
		return input;
	}
	else
	{
		int row, line;
		row = (input - 5) / 4;
		line = (input - 5) % 4;
		if(row % 2 == 0)
		{
			return (5 - line);
		}
		else
		{
			return (1 + line);
		}
	}
}

void disp(FINGERRECORD *link){
	link = link->next;
    for(int i = 0; link != NULL; i++){
        printf("%d\n",where(link->data));
        link = link->next;
    }
}

int main()
{ 
	FINGER f = 0;
    FINGERRECORD *head, *current, *tail;
    current = tail = (FINGERRECORD*)malloc(sizeof(FINGERRECORD));
    head = NULL;
    for(int i = 1;; i++){
        if(i == 1){
            head = current;
        }else{
            tail->next = current;
        }
        tail = current; 
        current = (FINGERRECORD*)malloc(sizeof(FINGERRECORD));
        FINGER ff = getReturn();
        if(ff == 0){
        	break;
        }else{
        	current->data = ff;
        }
    }
    tail->next = NULL;

    disp(head);
   return 0;
}

更新：发现代码第九行有个范围BUG，修改之后依然报错－＝

于是只保留核心代码……

#include <iostream>

typedef long long FINGER;

int where(FINGER input){
	if(input >= 1 && input <= 5)
	{
		return input;
	}
	else
	{
		int row, line;
		row = (input - 5) / 4;
		line = (input - 5) % 4;
		if(row % 2 == 0)
		{
			return (5 - line);
		}
		else
		{
			return (1 + line);
		}
	}
}

int main()
{ 
	FINGER  temp;
	while(1){
		std::cin >> temp;
		std::cout << where(temp) << std::endl;
	}
	
   return 0;
}

果然题目要求与标准答案不一致，又被坑了一次－＝
