hello world for u

Posted 2020-09-22

题目描述：

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 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.

输入：

There are multiple test cases.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.

输出：

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

样例输入：

helloworld!
ac.jobdu.com

样例输出：

h   !
e   d
l   l
lowor
a    m
c    o
.    c
jobdu.

 

代码：

#include<iostream>
#include<string.h>
using namespace std;
#define max 85
char s[2][max];

int main()
{
int len[2];
int n1, n2, n3;
int i, j;
cin >> s[0];
cin >> s[1];

len[0] = strlen(s[0]);
len[1] = strlen(s[1]);

for (int p = 0; p < 2; p++){
n1 = n3 = (len[p] + 2) / 3;
n2 = len[p] - 2 * n1;
for (i = 0; i < n1 - 1; i++)
{
cout << s[p][i];
for (j = 0; j < n2; j++) cout << " ";
cout << s[p][len[p] - 1 - i] << endl;
}
for (j = i; j < len[p] - i; j++)
cout << s[p][j];
cout << endl;
}

return 0;
}
