PAT (Advanced Level) Practice 1058 A+B in Hogwarts
1058 A+B in Hogwarts
If you are a fan of Harry Potter, you would know the world of magic has its own currency system -- as Hagrid explained it to Harry, "Seventeen silver Sickles to a Galleon and twenty-nine Knuts to a Sickle, it's easy enough." Your job is to write a program to compute A+B where A and B are given in the standard form of Galleon.Sickle.Knut
(Galleon
is an integer in [0,107], Sickle
is an integer in [0, 17), and Knut
is an integer in [0, 29)).
Input Specification:
Each input file contains one test case which occupies a line with A and B in the standard form, separated by one space.
Output Specification:
For each test case you should output the sum of A and B in one line, with the same format as the input.
Sample Input:
3.2.1 10.16.27
Sample Output:
14.1.28
running code:
version1:
#include<cstdio>
int main()
{
int a1,b1,c1;
int a2,b2,c2;
scanf("%d.%d.%d %d.%d.%d",&a1,&b1,&c1,&a2,&b2,&c2);
int s1=a1+a2,s2=b1+b2,s3=c1+c2;
if(s3>=29&&s2<17)
{
s3%=29;
s2++;
if(s2>=17)
{
s2%=17;
s1++;
}
}
else if(s3>=29&&s2>=17)
{
s3%=29;
s2=s2%17+1;
s1++;
}
else if(s2>=17)
{
s2%=17;
s1++;
}
printf("%d.%d.%d\n",s1,s2,s3);
}
version2:
#include<cstdio>
int main()
{
int a[3],b[3],c[3];
scanf("%d.%d.%d%d.%d.%d",&a[0],&a[1],&a[2],&b[0],&b[1],&b[2]);
int carry=0;
c[2]=(a[2]+b[2])%29;
carry=(a[2]+b[2])/29;//进位
c[1]=(a[1]+b[1])%17;
carry=(a[1]+b[1]+carry)/17;//进位
c[0]=a[0]+b[0]+carry;
printf("%d.%d.%d",c[0],c[1],c[2]);
return 0;
}
