Problem:
 Score : 400 points    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
