hdu_1030(数学题+找规律)

规律就是两个数字的level差+left差+right差

代码：

 #include<cstdio>

 #include<iostream>

 #include<cstring>

 #include<algorithm>

 #include<cmath>

 using namespace std;

 int main()

 {

     int a,b;

     while(~scanf("%d%d",&a,&b))

     {

         int i1,i2,j1,j2;

         int left1,left2,right1,right2;

         i1 = sqrt(a-)+;j1 = a-(i1-)*(i1-);

         i2 = sqrt(b-)+;j2 = b-(i2-)*(i2-);

         left1 = j1/+j1%; left2 = j2/+j2%;

         right1 = (*i1-j1)/+(*i1-j1)%; right2 = (*i2-j2)/+(*i2-j2)%;

         int ans = abs(i1-i2)+abs(left1-left2)+abs(right1-right2);

        // printf("i1 = %d; i2 = %d; j1 = %d; j2 = %d; left1 = %d; left2 = %d; right1 = %d; right2 = %d;\n",i1,i2,j1,j2,left1,left2,right1,right2);

         printf("%d\n",ans);

     }

     return ;

 }
