how is [5 5 5] false?
[5 5 5] can make a triangle, but not a *right* triangle (with one 90-degree angle). See the Wikipedia page definition.
This problem, and more similar but difficult ones, are covered in depth in the CUP challenge
not a solution to the problem. solution to the testcases.
I added a test case to nullify this "solution".
right triangle>a triangle with one 90 degree_angle?from this point,we can see the expression power of English sucks when compared to that of chinese
FYI, "right triangle" is American English, "right-angled triangle" (or "right-angle triangle") is British English. Neither expression reflects the 'power' of the language.
This presupposes issorted([a b c]).
