[abc117_b]Polygon
Problem Statement
Determine if an -sided polygon (not necessarily convex) with sides of length can be drawn in a two-dimensional plane.
You can use the following theorem:
Theorem: an -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 sides.
Constraints
- All values in input are integers.
Input
Input is given from Standard Input in the following format:
Output
If an -sided polygon satisfying the condition can be drawn, print Yes
; otherwise, print No
.
Sample Input 1
4
3 8 5 1
Sample Output 1
Yes
Since , it follows from the theorem that such a polygon can be drawn on a plane.
Sample Input 2
4
3 8 4 1
Sample Output 2
No
Since , it follows from the theorem that such a polygon cannot be drawn on a plane.
