B1027. 打印沙漏 (20)

Description:

本題要求你寫個程序把給定的符號打印成沙漏的形狀。例如給定17個“*”,要求按下列格式打印

*****
 ***
  *
 ***
*****

所謂“沙漏形狀”,是指每行輸出奇數個符號;各行符號中心對齊;相鄰兩行符號數差2;符號數先從大到小順序遞減到1,再從小到大順序遞增;首尾符號數相等。

給定任意N個符號,不一定能正好組成一個沙漏。要求打印出的沙漏能用掉盡可能多的符號。

Input:

輸入在一行給出1個正整數N(<=1000)和一個符號,中間以空格分隔。

Output:

首先打印出由給定符號組成的最大的沙漏形狀,最後在一行中輸出剩下沒用掉的符號數。

Sample Input:

19 *

Sample Output:

*****
  ***
   *
  ***
*****

A1031. Hello World for U (20)

Description:

Given any string of N (>=5) 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 n1characters, then left to right along the bottom line with n2 characters, and finally bottom-up along the vertical line with n3 characters. And more, we would like U to be as squared as possible -- that is, it must be satisfied that n1 = n3 = max { k| k <= n2 for all 3 <= n2 <= N } with n1 + n2 + n3 - 2 = N.

Input:

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:

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
