Description

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.

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`.

Constraints

-   All values in input are integers.
-   $3 \leq N \leq 10$
-   $1 \leq L_i \leq 100$

Sample 1 Input

4
3 8 5 1

Sample 1 Output

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

Sample 2 Input

4
3 8 4 1

Sample 2 Output

No
Since 8≥8=3+4+1, it follows from the theorem that such a polygon cannot be drawn on a plane.

Sample 3 Input

10
1 8 10 5 8 12 34 100 11 3

Sample 3 Output

No
