Convex Polygon

CodeChefOpen on judge ↗

Let's define a function on a set $A$= $(a_1, a_2, ... , a_k)$ with size k: **F($a_1, a_2, ... , a_k$)**. Imagine that we have sticks of lengths $a_1, a_2, ... , a_k$. $F(a_1,a_2,.....a_k) = 1$, if and only if a convex polygon can be created from these sticks, and 0 otherwise. We also define identity permutation over n elements as follows. $I_n$ = {1, 2, 3, .. n}. We want to know t
