I think the inequalities at the top of the problem must be backwards. In the example, c = 2*a, so c > a.
Hi William, Your right. I'd already changed. This should not affect the solution, though.
Many of your "Easy" sequence problems have been challenging and fun. But here I am confused. I get the correct solutions for Tests 1 through 3. For Test 4 (and higher) I have problems. My result for Test 4 is p = 209737287485879. When I try to calculate a, b and c from r and the given value of p_correct (using Python3 and math.isqrt to handle large integers) I fail to find integer values.
Have I missed some important point here?
The p_correct values contain only the last 12 digits.
It seems I stopped reading (or absorbing what I read) before the last line of the problem description. Thanks to Tim for the clarification.
Sorry, I haven't look at the comments lately. I thought no one's gonna answer this one. Thanks Tim, for the clarification...
I know I can't use symbolics, but I was just checking to see if my algorithm was correct. It matches the test suite for r <=10 (before needing to mod for the last 12 digits), but not for larger r's. It seems like it should be correct. I must be missing something. Not sure if you want to provide me with a hint.
HINT: An optimized solution can be obtained via Pell's equation.
Hi William, the output should be the perimeter, not the triangle sides…
