Given a matrix of size N x N. Print the elements of the matrix in the snake like pattern depicted below.

Example 1:

Input:
N = 3 
matrix[][] = {{45, 48, 54},
             {21, 89, 87}
             {70, 78, 15}}
Output: 45 48 54 87 89 21 70 78 15 
Explanation:
Matrix is as below:
45 48 54
21 89 87
70 78 15
Printing it in snake pattern will lead to 
the output as 45 48 54 87 89 21 70 78 15.

Example 2:

Input:
N = 2
matrix[][] = {{1, 2},
              {3, 4}}
Output: 1 2 4 3
Explanation:
Matrix is as below:
1 2 
3 4
Printing it in snake pattern will 
give output as 1 2 4 3.

code:

 vector<int> snakePattern(vector<vector<int> > matrix)
    {   
        vector<int> result;
   
        for(int i=0;i<matrix.size();i++)
        {
            if(i%2==0)
            {
                 for(int j=0;j<matrix[i].size();j++)
                  {
                    result.push_back(matrix[i][j]);
                  } 
            }
            else
            {
                 for(int j=matrix[i].size()-1;j>=0;j--)
                  {
                    result.push_back(matrix[i][j]);
                  } 
            }
          
            
        }
        
return result;
    }
