Enter three positive integers in the topic description to determine whether the three sides of the triangle can be formed. If not, output "NO ". If a triangle can be formed, which triangle can be determined? Output the corresponding triangle types "Equilateral", "Right", and "General" in sequence by equals, Right, and General ". Enter three integers a, B, and c separated by spaces in a row to indicate the length of the three sides of the triangle. The output corresponds to the triangle type. If a triangle cannot be formed, the output "NO" is displayed. If an equedge triangle is used, the output "Equilateral" is displayed. If a Right triangle is used, the output "Right" is displayed ", other triangles output "General ". Sample Input

3 4 5

Sample output
