    public void rotate(int[][] matrix) {
    for(int i=0,p=matrix.length-1;i<matrix.length/2;i++)
    {
    for(int j=0;j<matrix[0].length;j++)
    {
    int temp=0;
    temp=matrix[i][j];
    matrix[i][j]=matrix[p][j];
    matrix[p][j]=temp;
    }
    p--;
    }

        for(int i=0;i<matrix.length;i++)
        {
            for(int j=i;j<matrix[0].length;j++)
            {
                
                
                int temp=0;
                temp=matrix[i][j];
                matrix[i][j]=matrix[j][i];
                matrix[j][i]=temp;
