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 n1​ characters, 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

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

只要先把n1和n2確定出來，題目就變成了簡單的列印題

 1 #include<bits/stdc++.h>
 2 using namespace std;
 3 int main(){
 4     char word[100
 
];
 5     memset(word,0,sizeof(word));
 6     cin>>word;
 7     int n=strlen(word);
 8     int n1=(n+2)/3;
 9     int n2=n+2-n1*2;
10     int k=0;
11     for(int i=0;i<n1;++i){
12         if (i!=n1-1){
13             cout<<word[k];
14             for (int j=0;j<n2-2;++j){
15                 cout<<" ";
16             }
17             cout<<word[n-1-k]<<endl;
18             k++;
