The `Triangle Program'

Write a program to accept three (INTEGER) lengths and report back on whether these lengths could define an equilateral, isosoles or scalene triangle (3, 2 or 0 equal length sides) or whether they cannot form a triangle.

Demonstrate that the program works by classifying the following:

1. (1, 1, 1)
2. (2, 2, 1)
3. (1, 1, 0)
4. (3, 4, 5)
5. (3, 2, 1)
6. (1, 2, 4)
