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:
N
L_1 L_2 ... L_N

-----Output-----
If an N-sided polygon satisfying the condition can be drawn, print Yes; otherwise, print No.

-----Sample Input-----
4
3 8 5 1

-----Sample Output-----
Yes

Since 8 < 9 = 3 + 5 + 1, it follows from the theorem that such a polygon can be drawn on a plane.
