#include<iostream.h>
#include<string.h>
#include <stdio.h>
#include<math.h>
int main()
{
	int i,j,k,n,row,col;
	char s1[201];
	char s2[21][21];
	while(cin>>col)
	{
		if(col==0) break;
		gets(s1);
		n=strlen(s1);
		row=n/col;
		for(i=0;i<row;i++)
		{
			if(i%2==0)
			{
				j=0;
				while(j<col)
				{
					for(k=i*col;k<(i+1)*col;k++) { s2[i][j]=s1[k]; j++; }
				}				
			}	
		    else
			{
				j=0;
				while(j<col)
				{
					for( k=((i+1)*col-1) ; k>=i*col; k--) { s2[i][j]=s1[k]; j++; }
				}

		for(j=0;j<col;j++)
		{
			for(i=0;i<row;i++)
			{
				cout<<s2[i][j];
