脚本宝典收集整理的这篇文章主要介绍了1031 Hello World for U (20 分),脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
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.
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.
For each test case, print the input string in the shape of U as specified in the description.
helloworld!
h !
e d
l l
lowor
将一串字符串以U
型形式输出出来。
根据题意计算n1,n2,n3,这里n1等于n3,只要定义n1和n2即可。
计算方法:
已知:n1=n3=max {k | k≤n2 for all 3≤n2≤N },且n1+n2+n3-2=N
可得:(n1=n3=(N+2)/2)(结果向下取整)
(n2=N+2-n1-n3)
计算出n1和n2后,即可根据题目要求输出U
型图形(见代码)。
#include <iostream>
#include <string>
using namespace std;
int main()
{
string str;
cin >> str;
int n1, n2;
int N = str.length();
n1 = (N + 2) / 3;
n2 = N + 2 - (2 * n1);
for (int i = 0; i < n1 - 1; ++i)
{
// 输出第i个字符
cout << str[i];
// 输出中间的空格
for (int j = 0; j < n2 - 2; ++j) cout << " ";
// 输出倒数第i+1个字符
cout << str[N - 1 - i] << endl;
}
// 最后一行输出剩下的中间字符串
cout << str.substr(n1 - 1, n2) << endl;
return 0;
}
