Try replacing

**long** with

**long long**.

Also I'd suggest to use the "return 0" statement at the end of

**main** function.

And remove system("pause") from the end of your main function.

Everything else seems identical to my solution.

Let me know if it works.

A triangle is invalid if any side_length <= 0 or (sum of smaller 2 sides <= largest side).

A triangle is scalene if it is valid && all the sides are distinct.

The condition for invalid is wrong.

it should be T[0]+T[1] <= T[2].

Your code even does not pass the sample input.

What do you mean by

Code: Select all

```
else if(t1+t2<t3||t1+t3<t2||t2+t3<t1)
puts("Scalene");
```

Easy but a bit tricky.

it make me really angry. would u make a look at this. why it's getting wa!!

Code: Select all

```
#include<stdio.h>
int main()
{
long long int n,c=0,t1,t2,t3;
scanf("%lld",&n);
while(n--)
{
c++;
scanf("%lld %lld %lld",&t1,&t2,&t3);
printf("Case %lld: ",c);
if(t1<=0||t2<=0||t3<=0)
puts("Invalid");
else if(t1+t2<=t3||t2+t3<=t1||t1+t3<=t2)
puts("Invalid");
else if(t1==t2==t3)
puts("Equilateral");
else if(t1==t2||t2==t3||t1==t3)
puts("Isosceles");
else
puts("Scalene");
}
return 0;
}
```

Thank you for your help. newton.

You have declared variables as long int but you are taking input with %lld as long long int.

How can you hope that you will get Accepted.

The problem is really Easy if you think a little before post.

I have accepted after 16 submission!!!

But the main thing we need to do is to find the smallest, mid, and the max value. Then do what they want to do.

This one also helped me.

A triangle is invalid if any side_length <= 0 or (sum of smaller 2 sides <= largest side).

A triangle is scalene if it is valid && all the sides are distinct.
