题目: UVA - 11988Broken Keyboard (a.k.a. Beiju Text)(链表)
题目大意:某位程序员在用坏掉的键盘打字,这个键盘的home键和end键会是不是自己打印。然后现在给出这样的一串文字,要求你打印出之后会在屏幕上显示的字符串。
解题思路:home键是跳到这一行的开头开始打印,end键是跳到这一行的末尾开始打印。用一个链表将home和end之后的字符串串起来,之后在按顺序输出就可以了。碰到home键后面的字符串(从当前的home到另一个home或是end或是结束符为止)放到链表的前面。end的放后面。
代码:
#include <iostream>
#include <algorithm>
#include <string>
#include <list>
using namespace std;
string str;
list<string> l;
list<string>::iterator it;
void solve () {
int n;
string tmp;
n = 0;
for (int i = 0; i < str.length(); i++, n++)
if (str[i] == ']' || str[i] == '[')
break;
tmp = "";
tmp = str.substr (0, n);
l.push_back(tmp);
for (int i = 0; i < str.length(); i++) {
if(str[i] == '[') {
n = 0;
tmp = "";
for (int j = i + 1; j < str.length() && str[j] != ']' && str[j] != '['; j++)
n++;
tmp = str.substr(i + 1, n);
l.push_front(tmp);
i += n;
} else if (str[i] == ']') {
n = 0;
tmp = "";
for (int j = i + 1; j < str.length() && str[j] != '[' && str[j] != ']'; j++)
n++;
tmp = str.substr(i + 1, n);
l.push_back(tmp);
i += n;
}
}
}
/*
Print_it (const string &a) {
cout<<a;
}*/
int main () {
while (cin>>str) {
solve ();
// for_each (l.begin(), l.end(), Print_it);
for (it = l.begin(); it != l.end(); it++)
cout<<*it;
cout<<endl;
l.erase(l.begin(), l.end());
}
return 0;
