这段代码有错
修改前:
```cpp
void mul(){
for(int i=0;i<=len-1;i++)
{
num[i]*=2;
num[i+1]+=num[i]/10;
num[i]%=10;
}
len++;
while(num[len-1]==0&&len>1)len--;
}
```
修改后:
```cpp
void mul(){
for(int i=0;i<=len-1;i++) num[i]*=2;
for(int i=0;i<=len-1;i++)
{
num[i+1]+=num[i]/10;
num[i]%=10;
}
len++;
while(num[len-1]==0&&len>1)len--;
}
```
