    HINT

    分析；
    就是01互换，然后对比两个串的异同。

    AC代码：

     1 #include<cstdio>
 2 #include<algorithm>
 3 #include<cstring>
 4 #include<queue>
 5 #include<iostream>
 6 #include<stack>
 7 #include<map>
 8 #include<string>
 9 using namespace std;
10 char ch1[1050], ch2[1050];
11 int main(){
12     int n;
13     while(~scanf("%d", &n)){
14         scanf("%s%s", ch1, ch2);
15         int l = strlen(ch1);
16         if(n%2 == 1)
17             for(int i = 0; i < l; i++)
18                 if(ch1[i] == '1')
19                     ch1[i]--;
20                 else if(ch1[i] == '0')
21                     ch1[i]++;
22         if(strcmp(ch1, ch2) == 0)
23             printf("Deletion succeeded
");
24         else
25             printf("Deletion failed
");
26     }
27     return 0;
28 }
