以蛇模式打印矩阵的 Javascript 程序

给定一个 nxn 矩阵。在给定的矩阵中，您必须以蛇形模式打印矩阵的元素。

例子 ：

Input :mat[][] = { {10, 20, 30, 40},
                   {15, 25, 35, 45},
                   {27, 29, 37, 48},
                   {32, 33, 39, 50}};
              
Output : 10 20 30 40 45 35 25 15 27 29
         37 48 50 39 33 32 

Input :mat[][] = { {1, 2, 3},
                   {4, 5, 6},
                   {7, 8, 9}};
Output : 1 2 3 6 5 4 7 8 9

我们遍历所有行。对于每一行，我们检查它是偶数还是奇数。如果是偶数，我们从左到右打印，否则从右到左打印。

Javascript

  
// Javascript program to print
// matrix in snake order
let M = 4;
let N = 4;
  
function print(mat)
{
      
    // Traverse through all rows
    for(let i = 0; i < M; i++) 
    {
          
        // If current row is even, print from
        // left to right
        if (i % 2 == 0) 
        {
            for(let j = 0; j < N; j++)
                document.write(mat[i][j] + " ");
  
        // If current row is odd, print from
        // right to left
        } 
        else
        {
            for(let j = N - 1; j >= 0; j--)
                document.write(mat[i][j] + " ");
        }
    }
}
  
// Driver code
let mat = [ [ 10, 20, 30, 40 ],
            [ 15, 25, 35, 45 ],
            [ 27, 29, 37, 48 ],
            [ 32, 33, 39, 50 ] ];
  
print(mat);

输出 ：

10 20 30 40 45 35 25 15 27 29 37 48 50 39 33 32
