Canadian Computing Competition: 2014 Stage 1, Junior #1

You have trouble remembering which type of triangle is which. You write a program to help. Your program reads in three angles (in degrees).

• If all three angles are ~60~, output Equilateral.
• If the three angles add up to ~180~ and exactly two of the angles are the same, output Isosceles.
• If the three angles add up to ~180~ and no two angles are the same, output Scalene.
• If the three angles do not add up to ~180~, output Error.

Input Specification

The input consists of three integers, each on a separate line. Each integer will be greater than ~0~ and less than ~180~.

Output Specification

Exactly one of Equilateral, Isosceles, Scalene or Error will be printed on one line.
