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

Solution in Python (3.4.3) (judge verdict: Accepted)

N = int(input())
a = list(map(int,input().split()))
amod4 = [0,0,0,0]
for i in range(N):
    if a[i]%4 == 0:
        amod4[0]+=1
    elif a[i]%4 == 1:
        amod4[1]+=1
    elif a[i]%4 == 2:
        amod4[2]+=1
    else:
        amod4[3]+=1
if amod4[1]+amod4[3] <= amod4[0]:
    print("Yes")
elif amod4[1]+amod4[3] == amod4[0]+1 and amod4[2] == 0:
    print("Yes")
else:
    print("No")
