Triangle Property
Question:
In mathematics, the triangle inequality states
that for any triangle, sum of the lengths
of any two sides must be greater
than the length of the remaining side.
You are given the sides of three triangles,
how many of them comply the triangle property?
Input specification:
You will be given 3 integers in three lines.
(s1, s2 and s3) where 0 ≤ (s1, s2 and s3) ≤ 1 million.
Output specification:
Show one number, the number of triangles.
Sample Input I
3 4 5
12 5 13
5 10 15
|
Sample Input II
19 9 8
6 11 14
3 17 12
|
Sample Output I
2
|
Sample Output II
1
|
Explanation:
for the first sample: the third number triple does not
comply the triangle property 15 < 5+10.
The other two number triples are OK.
For the second sample, only the the second
input complies the triangle property 14, 6, 11.
