計算三個刻度的密碼鎖,要打開總共需要轉幾度

[心得]

1.順和逆時針指的都是轉盤,刻度移動的方向和他相反 (圖要看仔細)

2.所轉的刻度數還要換成degree

 

#include <stdio.h>

int main()
{
    int start,first,second,third;
    int degree;
   
    while(scanf("%d %d %d %d",&start,&first,&second,&third))
    {
        if(!start &&!first &&!second &&!third) break;
        degree=1080;
       
        if(first>start) degree+=(start+40-first)*9;
        else degree+=(start-first)*9;
       
        if(first>second) degree+=(second+40-first)*9;
        else degree+=(second-first)*9;
       
        if(third>second) degree+=(second+40-third)*9;
        else degree+=(second-third)*9;
       
        printf("%d\n",degree);
    }
   
    return 0;
}
