此贴结。
```
if(dep[x] < dep[y]){
swap(x, y);
}
int dis = dep[x] - dep[y];
for(int i = 0; dis != 0; i++){
if(dis % 2 == 1){
y = fa[y][i];
}
dis /= 2;
}
```
改为
```cpp
if(dep[x] < dep[y]){
swap(x, y);
}
int dis = dep[x] - dep[y];
for(int i = 0; dis != 0; i++){
if(dis % 2 == 1){
x = fa[x][i];
}
dis /= 2;
}
```
