lrj的输入输出挂
inline int readint(){//只能读取非负int char c=getchar();while(!isdigit(c)) c=getchar();int x=0;while(isdigit(c)){x=x*10+c-'0';c=getchar();}return x;}int buf[10];//声明成全局变量可以减少开销inline void writeint(int i){//只能输出非负int int p=0;if(i==0) p++;//特殊情况:i等于0的时候需要输出0,而不是什么也不输出else while(i){buf[p++]=i%10;i/=10; } for(int j=p-1;j>=0;j--) putchar('0'+buf[j]);//逆序输出 }
一般读入挂
inline int read(){ int x=0,f=1;char ch=getchar(); while(ch<'0'||ch>'9'){if(ch=='-')f=-1;ch=getchar();} while(ch>='0'&&ch<='9'){x=x*10+ch-'0';ch=getchar();} return x*f;}
