A triangle is a geometric shape with three positive sides. However, any given three sides won’t necessarily form a triangle. The three sides must form a closed region. Triangles are categorized depending on the values of the sides of a valid triangle. In this problem you are required to determine the type of a triangle.

 

  
  Input    
 

The first line of input will contain a positive integer T<20, where T denotes the number of test cases. Each of the next T lines will contain three 32 bit signed integer.

  
     
  Output  
 

For each case of  input there will be one line of output. It will be formatted as:
Case #{x}: {triangle type}. Where x denotes the case number being processed and {triangle type} is the type of the triangle..{triangle type} will be one of the following, depending on the values of the three sides:

    • Invalid - The three sides can not form a triangle
    • Equilateral  - All three sides of valid triangle are equal
    • Isosceles  - Exactly two of the sides of a valid triangle are equal.
    • Scalene - No pair of sides are equal in a valid triangle.
