The King of Byteland wants to grow his territory by conquering other countries. To prepare his heirs for the future, he decides they must work together to capture each country.

The King has an army, , of battalions; the battalion has soldiers. For each battle, the heirs get a detachment of soldiers to share but will fight amongst themselves and lose the battle if they don't each command the same number of soldiers (i.e.: the detachment must be divisible by ). If given a detachment of size , the heirs will fight alone without any help.

The battalions chosen for battle must be selected in the following way:

- A subsequence of battalions must be selected (from the battalions in army ).
- The battle will have a squad of soldiers from the selected battalion such that its size is divisible by .

The soldiers within a battalion have unique strengths. For a battalion of size , the detachment of soldiers is *different* from the detachment of soldiers

The King tasks you with finding the number of ways of selecting detachments of battalions to capture countries using the criterion above. As this number may be quite large, print the answer modulo .

**Input Format**

The first line contains two space-separated integers, (the number of battalions in the King's army) and (the number of countries to conquer), respectively.

The second line contains space-separated integers describing the King's army, , where the integer denotes the number of soldiers in the battalion ().

**Constraints**

- holds for test cases worth at least of the problem's score.

**Output Format**

Print the number of ways of selecting the detachments of battalions modulo .

**Sample Input**

```
3 2
3 4 5
```

**Sample Output**

```
20
```

**Explanation**

First, we must find the ways of selecting of the army's battalions; then we must find all the ways of selecting detachments for each choice of battalion.

*Battalions :*

has soldiers, so the only option is an empty detachment ().

has soldiers, giving us detachment options ( and ).

So for this subset of battalions, we get possible detachments.

*Battalions :*

has soldiers, so the only option is an empty detachment ().

has soldiers, giving us detachment options (, , , , , ).
So for this subset of battalions, we get possible detachments.

*Battalions :*

has soldiers, giving us detachment options ( and ).

has soldiers, giving us detachment options (, , , , , ).

So for this subset of battalions, we get possible detachments.

In total, we have ways to choose detachments, so we print , which is .
