Problem Statement

Determine if an NN-sided polygon (not necessarily convex) with sides of length L1,L2,...,LNL_1, L_2, ..., L_N can be drawn in a two-dimensional plane.

You can use the following theorem:

Theorem: an NN-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 N1N-1 sides.

Constraints

  • All values in input are integers.
  • 3N103 \leq N \leq 10
  • 1Li1001 \leq L_i \leq 100

Input

Input is given from Standard Input in the following format:

NN

L1L_1 L2L_2 ...... LNL_N

Output

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

Yes

Since 8<9=3+5+18 < 9 = 3 + 5 + 1, it follows from the theorem that such a polygon can be drawn on a plane.

3 8 4 1
No

Since 88=3+4+18 \geq 8 = 3 + 4 + 1, it follows from the theorem that such a polygon cannot be drawn on a plane.
