题目描述
Determine if an N-sided polygon (not necessarily convex) with sides of length L_1, L_2, ..., L_N can be drawn in a two-dimensional plane.
You can use the following theorem:
Theorem: an N-sided polygon satisfying the condition can be drawn if and only if the longest side is strictly shorter than the sum of the lengths of the other N-1 sides.
Constraints
- All values in input are integers.
- $3 \leq N \leq 10$
- $1 \leq L_i \leq 100$
Input
Input is given from Standard Input in the following format:
