#include<iostream>
using namespace std;
int main()
{
	char a[110][60],b[110];
	int i,j,x,m,n,s,q,r;
	cin>>n>>m;
	for(i=0;i<m;i++)
	for(j=0;j<n;j++)
		cin>>a[i][j];
	for(i=0;i<m;i++)//求出各行中的逆序数数目
	{
		int t=0;
		for(j=0;j<n-1;j++)
		{
			for(x=1;x<n-j;x++)
			if(a[i][j]>a[i][j+x]) t++;
		}
		b[i]=t;
	}
	for(s=0;s<=m;s++)//用冒泡法根据逆序数数目大小按行将数组排序
	{
		for(i=0;i<m-1;i++)
			if(b[i]>b[i+1])
			{
				q=b[i];b[i]=b[i+1];b[i+1]=q;
				for(j=0;j<n;j++)
				{r=a[i][j];a[i][j]=a[i+1][j];a[i+1][j]=r;}
			}
	}
	for(i=0;i<m;i++)
	{for(j=0;j<n;j++)
		cout<<a[i][j];
	cout<<endl;}
	return 0;
}
