On a broken keyboard, some of the keys are worn out. So when you type some sentences, the characters corresponding to those keys will not appear on screen.
Now given a string that you are supposed to type, and the string that you actually type out, please list those keys which are for sure worn out.
Input Specification:
Each input file contains one test case. For each case, the 1st line contains the original string, and the 2nd line contains the typed-out string. Each string contains no more than 80 characters which are either English letters [A-Z] (case insensitive), digital
numbers [0-9], or "_" (representing the space). It is guaranteed that both strings are non-empty.
Output Specification:
For each test case, print in one line the keys that are worn out, in the order of being detected. The English letters must be capitalized. Each worn out key must be printed once only. It is guaranteed that there is at least one worn out key.
Sample Input:
Sample Output:

我的c++程序:
#include<iostream> #include<string> #include<array> using namespace std; int main() { int i = 0,j=0,n=0; string first, second;//first应该的字符串,second实际输入的字符串 array<char, 80> result;//漏掉的字符 cin >> first>>second; while (i < first.size())//小写转大写 { if (first[i] >= 'a'&&first[i] <= 'z') { first[i] = first[i] - 32; } i++; } while (j< second.size())//小写转大写 { if (second[j] >= 'a'&& second[j] <= 'z') { second[j] = second[j] - 32; } j++; } i = 0,j=0; for (auto p : first) { if (second.find(p) == -1)//在实际输入的字符串里查找漏掉的的字符,没找到返回-1 { result.at(i)=p;//把漏掉的字符串添加进result数组 i++; } } n = i; for (i = 0; i <n;i++)//把重复的字符串标记为'*' { for (j = i+1; j < n; j++) { if (result[i] == result[j]) { result[j] = '*'; } } } for (i = 0; i <n; i++) { if (result[i] != '*')//输出不重复的字符 { cout << result[i]; } } //system("pause"); return 0; }
python程序:
l=raw_input() k=raw_input() re="" s=[] s1=[] for i in l: if i.upper() not in s: s.append(i.upper() ) for i in k: if i.upper() not in s1: s1.append(i.upper() ) for i in s: if i not in s1: re=re+i print re
