分析:
简单题,调整数组的输出次序就可以了。
输入数组长度为len。n1 = n3 = (len+2)/3; n2 = len - n1 - n3;
第一行最左边对应的是原数组的第一个字符,最后边对应的是原数组的最后一个字符。总共输出n1行。
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.
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
参考代码:
#include<iostream> #include<string.h> using namespace std; #define max 85 char input[max]; int main() { int len; int n1,n2,n3; int i,j; cin>>input; len = strlen(input); n1 = n3 = (len + 2) / 3 ; n2 = len - 2*n1; for(i=0; i<n1-1; i++) { cout<<input[i]; for(j=0; j<n2; j++) cout<<" "; cout<<input[len-1-i]<<endl; } for(j=i; j<len-i; j++) cout<<input[j]; cout<<endl; return 0; }
