The length of one side of a triangle must be greater than the positive difference and less than the sum of the lengths of the other
two sides. For example, if it is given that the length of one side is 3 and the length of another side is 4, then you know that the length
of the third side must be greater than 4 − 3 = 1 and less than 4 + 3 = 7.DON’T FORGET
