Given any string of N (≥) characters, you are asked to form the characters into the shape of U. For example, helloworld can be printed as:

h  d
e  l
l  r
lowo

That is, the characters must be printed in the original order, starting top-down from the left vertical line with n?1?? characters, then left to right along the bottom line with n?2?? characters, and finally bottom-up along the vertical line with n?3?? characters. And more, we would like U to be as squared as possible -- that is, it must be satisfied that n?1??=n?3??=max { k | kn?2?? for all 3 } with n?1??+n?2??+n?3??2=N.

Input Specification:

Each input file contains one test case. Each case contains one string with no less than 5 and no more than 80 characters in a line. The string contains no white space.

Output Specification:

For each test case, print the input string in the shape of U as specified in the description.

Sample Input:

helloworld!

Sample Output:

h   !
e   d
l   l
lowor
 1 #include <iostream>
 2 #include <string>
 3 using namespace std;
 4 int main()
 5 {
 6     string str, s;
 7     cin >> str;
 8     int m = (str.length() + 2) / 3;
 9     s.assign(str.length() - 2 * m,  );
10     for(int i=0;i<m-1;++i)
11         cout << str[i] << s << str[str.length() - i - 1] << endl;
12     s.assign(str.begin() + m - 1, str.end() - m + 1);
13     cout << s << endl;
14     return 0;    
15 }
