Problem: Haiku is a short form of Japanese poetry. A Haiku consists of three phrases with 5, 7 and 5 syllables, in this order.

Iroha is looking for X,Y,Z-Haiku (defined below) in integer sequences.

Consider all integer sequences of length N whose elements are between 1 and 10, inclusive. Out of those 10^N sequences, how many contain an X,Y,Z-Haiku?

Here, an integer sequence a_0, a_1, ..., a_{N-1} is said to contain an X,Y,Z-Haiku if and only if there exist four indices x, y, z, w (0 ≦ x < y < z < w ≦ N) such that all of the following are satisfied:

* a_x + a_{x+1} + ... + a_{y-1} = X
* a_y + a_{y+1} + ... + a_{z-1} = Y
* a_z + a_{z+1} + ... + a_{w-1} = Z



Since the answer can be extremely large, print the number modulo 10^9+7.

Constraints

* 3 ≦ N ≦ 40
* 1 ≦ X ≦ 5
* 1 ≦ Y ≦ 7
* 1 ≦ Z ≦ 5

Input

The input is given from Standard Input in the following format:


N X Y Z


Output

Print the number of the sequences that contain an X,Y,Z-Haiku, modulo 10^9+7.

Solution (in CPP):

Solution:
#include<bits/stdc++.h>
using namespace std;
const long long mo=1e9+7;
int n,x,y,z,hk,sum;
long long ans,dp[45][1<<18];
int main(){

	memset(dp,0,sizeof dp);
	hk=1<<x+y+z-1;
    hk|=1<<y+z-1;
    hk|=1<<z-1;
	sum=(1<<x+y+z)-1;
	dp[0][0]=1; ans=1;
	for(int i=1;i<=n;i++){
		ans=ans*10%mo;

		  	int now=(j<<k)|(1<<k-1); 
			now&=sum;// avoid"now"boom
		  	if((now&hk)!=hk) 
			  dp[i][now]=(dp[i][now]+dp[i-1][j])%mo;

	return 0;
