Mehta is a forever alone and desperate guy. He has a crush on N girls of his society. He wants to impress them all and so he needs to do their task collectively.All the girls give him a number which he stores in an array named A of size N. To do their task, he has to report the number of triplets (i,j,k) in the array A, with  i < j < k such that the triplets have at least one prime digit in common.

Input & Output:
The first line of the input contains an integer N. The next N lines has a number on each, which denote the array A.

You need to print on one line, the number of triples with the condition mentioned in the problem statement.

Constraints:

1 ≤ N ≤  10 ^ 5
0 ≤ A[i] ≤ 10  ^ {18}  for all index i in the array A.

Sample Input:

5
21
22
23
24
25

Sample Output:
10

SAMPLE INPUT
5
21
22
23
24
25

SAMPLE OUTPUT
10

Explanation

In the given sample each i,j,k has one prime digit common that is 2. So, total triplets are 5C3 which is 10.
combinations = [0]*100005

def combi():
	combinations[3]=1
	temp = 1
	for i in range(4,100000):
		temp = (temp*i)/(i-3)
		combinations[i] = temp
		
	

combi()
n = input()

a = [0]*100005
count = [0]*16

for i in range (0,n):
	a[i] = input()
	ac = a[i]
	c = 0 
	while(ac>0):
		if(ac%10==2):
			c = c|1
		if(ac%10==3):
			c = c|2			
		if(ac%10==5):
			c = c|4			
		if(ac%10==7):
			c = c|8
		ac = ac/10
		
	count[c] += 1
ans = 0
for i in range (1,16):
	j = i
	popcount = 0
	while (j>0):
		popcount +=1
		j = j - (j&-j)
	total =0
	for j in range (i,16):
		if((j&i)==i):
			total += count[j]
	
	if(popcount%2==0):
		ans -= combinations[total]
	elif(popcount%2==1):
