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 de ll rlowoThat 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. Andmore, 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>using namespace std;int main(int argc, char** args) {string s;while (cin >> s && s.size() >= 5 && s.size() <= 80) {int len = s.size();int height = (len - 2) / 3;int width = len - 2 * height;for (int i = 0; i < height; ++ i) {cout.setf(ios::left);cout.width(width - 1);cout << s[i];cout << s[len - (i + 1)] << endl;if (i == (height - 1)) {string substr = s.substr(height, width);cout << substr << endl;}}}}代码没有提交过,不知道能不能AC。[/code]
