Takahashi melted and mixed $A$ grams of gold and $B$ grams of silver $(0 \leq A,B,\ 0 \lt A+B)$ to produce new metal.

What metal did he produce: pure gold, pure silver, or an alloy?

Formally, the product is called as follows.

- Pure gold, if $0 \lt A$ and $B=0$.
- Pure silver, if $A=0$ and $0 \lt B$.
- An alloy, if $0 \lt A$ and $0 \lt B$.

- $0 \leq A,B \leq 100$
- $1 \leq A+B$
- All values in input are integers.

Input is given from Standard Input in the following format:

$A$ $B$

If the product is pure gold, print `Gold`

; if it is pure silver, print `Silver`

; if it is an alloy, print `Alloy`

.

Alloy

We have $0 \lt A$ and $0 \lt B$, so the product is an alloy.

Gold

We have $0 \lt A$ and $B=0$, so the product is pure gold.

0 100

Silver

We have $A=0$ and $0 \lt B$, so the product is pure silver.
