连等号好像是不能用的，中间加个&&试试吧

还是不输出
但谢谢了
```
#include <bits/stdc++.h>
using namespace std;
int main(){
char a[10];
int map[3][3];
memset(map,-1,sizeof(map));
scanf("%s",&a);
for(int i=0;i<strlen(a);i++){
int x=a[i]-'0'-1;
map[x/3][x]=i%2; //0:xiaoa 1:uim
}
for(int i=0;i<3;i++){
if((map[i][0]==map[i][1])&&(map[i][1]==map[i][2])){
if(map[i][0]==1){
printf("uim wins.");
}else if(!map[i][0]){
printf("xiaoa wins.");
}
return 0;
}
if((map[0][i]==map[1][i])&&(map[1][i]==map[2][i])){
if(map[0][i]==1){
printf("uim wins.");
}else if(!map[i][0]){
printf("xiaoa wins.");
}
return 0;
}
}
if((map[0][0]==map[1][1])&&(map[1][1]==map[2][2])){
if(map[0][0]==1){
printf("uim wins.");
}else if(!map[0][0]){
printf("xiaoa wins.");
}
return 0;
}
if((map[0][2]==map[1][1])&&(map[1][1]==map[2][0])){
if(map[0][2]==1){
printf("uim wins.");
}else if(!map[0][0]){
printf("xiaoa wins.");
}
return 0;
}
printf("drew.");
return 0;

```cpp
for(int i=0;i<strlen(a);i++){
int x=a[i]-'0'-1;
map[x/3][x]=i%2; //0:xiaoa 1:uim
}
```
这个循环他死了=。=
然后把所有的if（map[][]==1）改成if（map[][]）他就输出了~~但是答案不对~~

如果改成if（map[][]）
会有问题吧
因为值为-1是判断也为真

如果将
```
map[x/3][x]=i%2;
```
改为
```
map[x/3][x%3]=i%2;
```
如何？
却还是不输出

@[13858077854meng](/space/show?uid=116304)
改成
```cpp
int qwq=i%2;//改成临时变量他就不死了，我也不知道为啥
mep[x/3][x]=qwq;
```
