Hi Team,
I am getting error after submitting as,
"We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly"
But completion bar has been incremented.
Thanks and Have a Good DaY
Well I don't know why I can't pass the test
could anyone help
function c = right_triangle_sides(p)
c = {};
k=1;
for i=1:ceil(p/3)
for j=i:ceil((pi)/2)
if i^2+j^2==(pij)^2
c(k)=mat2cell([i j pii],1);
k=k+1;
end
end
end
end
To creator of this group,
Please check the test case 3 in the Problem of calculating side length from area of triangle. One ';' is missing which is not allowing the case to pass for correct solution.
This problem really highlights problems with the Cody scoring system. The score using a double for loop to brute force the lengths beats out a single for loop using equations. I tested my code in Matlab vs double loops and it's faster than most double loops I tested by several orders of magnitude for larger numbers (p>1000). There is also some sort of caching going on where my code gets orders of magnitude faster again if ran a few times vs most double for loops.
There is one exception with a double loop that is really fast by Hung Hoang. They use the for loops in a way that doesn't make it O^2.

I think, the statement of the problem is not complete. The reference problem is not available. I know very well about right angle triangles but I do not have the idea on how to find the solutions. Please help me out.
Hi Castillo,
it is just iteration of 3 sides using perimeter and summing up the three iteration variable for perimeter check then for right angle triangle check (Pythagoras)...
Hope this helped you...(:

Works, but is horribly inefficient especially for higher p...

solution using a Neural Network Toolbox function ;)
