Given three numbers a, b and c, can we use a, b and c as the length of each side to make up a triangle?  for example, given 1.1, 1.1 and 1.1, we can make up an equilateral triangle whose side is 1.1.
But given 1 , 1 and 10, we cannot make up a triangle.

one line with three numbers a, b and c

YES if we can use a, b and c to make up a triangle and NO if we cannot
