Problem Statement

We have a sequence of length N, a = (a_1, a_2, ..., a_N).
Each a_i is a positive integer.

Snuke's objective is to permute the element in a so that the following condition is satisfied:

For each 1 ≤ i ≤ N - 1, the product of a_i and a_{i + 1} is a multiple of 4.

Determine whether Snuke can achieve his objective.

Constraints

2 ≤ N ≤ 10^5

a_i is an integer.

1 ≤ a_i ≤ 10^9

Input

Input is given from Standard Input in the following format:

N
a_1 a_2 ... a_N

Output

If Snuke can achieve his objective, print Yes; otherwise, print No.

Sample Input 1

3
1 10 100

Sample Output 1

Yes

One solution is (1, 100, 10).

Sample Input 2

4
1 2 3 4

Sample Output 2

No

It is impossible to permute a so that the condition is satisfied.

Sample Input 3

3
1 4 1

Sample Output 3

Yes

The condition is already satisfied initially.

Sample Input 4

2
1 1

Sample Output 4

No

Sample Input 5

6
2 7 1 8 2 8

Sample Output 5

Yes

#include <stdio.h>


int main(void){
	int n;
	scanf("%d",&n);
	int a[n];
	for(int i=0;i<n;i++) scanf("%d",&a[i]);
	
	int kisuu,ni,yon;
	for(int i=0;i<n;i++){
		if(i%4==0){yon++;}
		else if(i%2==0){ni++;}
		else{kisuu++;}
	}
	int answer=0;
	if(n%2!=0&&(n-ni+1)/2<kisuu){answer=0;}
	if(n%2==0&&(n-ni)/2<kisuu){answer=0;}
	
	if(answer==1){
		printf("YES");
	}else{printf("NO");}
	return 0;
