How to determine for a maximum of two comparisons whether there is a triangle with sides of length a, b and c?
Given three numbers: a, b, c. How to determine for a maximum of two comparisons whether there is a triangle with sides of length a, b and c?
In the case of a+b>c, a+c>b, b+c>a, (a>0, b>0, c>0), everything is clear, but how to do it for 2 comparisons?
Ps the question is not educational, met in preparation for sobes :)
