private testcases are present. there is no way im going to know the testcases for which my code fails
Somnath Rakshit
Oct 15, 2015 20:13
black box testing is done on my code
Somnath Rakshit
Oct 15, 2015 20:12
why?

it wont

t is the no. of testcases
Somnath Rakshit
Oct 15, 2015 20:06
int t;
long long min=9999999999,i,m[4],c[3];
scanf("%d",&t);
while(t--)
{
scanf("%lld\n%lld\n%lld",&c[0],&c[1],&c[2]);
qsort(c,3,sizeof(c[0]),compare);
m[0]=(c[0]+c[1]+c[2])/3;
m[1]=(c[0]+c[1]);
m[2]=(c[2]+c[1]);
m[3]=(c[0]+c[2]);
for(i=0;i<4;i++)
if(m[i]<min)
min=m[i];
printf("%lld\n",min);
}

What was your fault that you found out?
Somnath Rakshit
Oct 15, 2015 19:46
Yes. I set up the formula and submitted.
Somnath Rakshit
Oct 15, 2015 19:46
No idea.But this answer was rejected.

min(trunc((a+b+c)/3) , a+b) is not the answer. It doesn't work always.
Somnath Rakshit
Oct 15, 2015 19:46
We cannot assume a<=b<=c
Somnath Rakshit
Oct 15, 2015 19:46
The problem says that for the given testcase, the one possible way to form the words is RRG, RGB, GRB, BGR where R,G,B denote the letters of the words. We cannot form more than 4 words with the given number of letters. The question says What maximum number of words can be formed if we have the given number of letters?
Somnath Rakshit
Oct 15, 2015 19:46
The problem has just been updated. The placement of letters do not matter. All 3 letter words which does not have all the letters same are allowed.
Somnath Rakshit
Oct 15, 2015 19:46
But then, how is the answer 4 for when a,b,c are equal to 5,4,3?
Somnath Rakshit
Oct 15, 2015 19:46
The given sample answer says that if we have 5 R, 4 G and 3 B, then the answer will be 4. RRG, RGB, GRB, BGR.
Somnath Rakshit
Oct 15, 2015 19:46
I need 3 letter words only.
