【PAT甲级】1031 Hello World for U (20 分)

题意:

输入一个字符串长度为5~80,以‘U‘型输出,使得底端一行字符数量不小于侧面一列,左右两列长度相等。

trick:

不把输出的数组全部赋值为空格为全部答案错误,可能不赋值数组里值为0,赋值后是‘ ‘,空格的ascii是32,初读题面时并没有看到要输出空格,因为打印0其实效果看起来好像一样。。。

代码:

#define HAVE_STRUCT_TIMESPEC
#include<bits/stdc++.h>
using namespace std;
string s;
char a[87][87];
int main(){
memset(a,‘ ‘,sizeof(a));
cin>>s;
int n=s.size();
int x=(n+2)/3;
for(int i=1;i<=x;++i)
a[i][1]=s[i-1];
for(int i=x+1;i<=n-x;++i)
a[x][i-x+1]=s[i-1];
for(int i=x;i>=1;--i)
a[i][n-2*x+2]=s[n-i];
for(int i=1;i<=x;++i){
for(int j=1;j<=n-2*x+2;++j)
cout<<a[i][j];
if(i!=x)
cout<<"\n";
}
return 0;
}
