Given two strings a and b, sometimes I want to determine which one of the three statements: a < b, a == b or a > b is true.
In a language like C or C++, I will get an int value v after one invoking of the corresponding function or method. Then I can determine which of the above statements is true by examining whether v < 0, v == 0 or v > 0.
But in Go I have to do at least two comparisons (e.g. first test a < b then test a == b) to find out which one of the three statements is true.
My question is that is there a way in Go so that I can just do a single comparison?
It turns out that this feature is called three way comparison.
