# Determine if triangle with given sides is invalid, equilateral, isoceles or scalene.
#
# Variables:
#
# $a0 - side a (int)
# $a1 - side b (int)
# $a2 - side c (int)
# $v0 - enum 0: scalene, 1: isoceles, 2: equilateral, 3: invalid
# $t0 - a == b
# $t1 - b == c
# $t5 - a == b && b == c (equilateral)
# $t6 - a == b || b == c (isoceles, if not above)
