As every March 29th, Juan leaves his house and heads towards the home of Jacobo, his best buddy, to celebrate the date in style, as one would expect. However, a malicious step stands in his way. In an unexpected turn of events, the step causes Juan to fall, a spectacle both dramatic and embarrassing, while it lets out a stony laugh that fits its role as the protagonist's arch-nemesis. As a result of the fall, Juan breaks his femur in two different places, resulting in three fragments of lengths $$$a$$$, $$$b$$$, and $$$c$$$.
While waiting for medical services, Juan wonders if he could form a non-degenerate triangle with these bone fragments.
The input consists of several cases. Each case consists of three natural numbers $$$a, b, c$$$ separated by spaces. Each case ends with a newline.
Print one line per case with the word "si" if Juan can form a non-degenerate triangle with the bone fragments and the word "no" otherwise.
$$$0 \leq a, b, c \lt 10^8$$$
