读入优化(int)
1 inline int getint() 2 { 3 int x=0,f=1;char ch=getchar(); 4 while(ch>'9'||ch<'0'){if(ch=='-')f=-1;ch=getchar();} 5 while(ch>='0'&&ch<='9'){x=x*10+ch-'0';ch=getchar();} 6 return x*f; 7 }
读入优化(long long)
1 inline int getLL() 2 { 3 long long x=0,f=1;char ch=getchar(); 4 while(ch>'9'||ch<'0'){if(ch=='-')f=-1;ch=getchar();} 5 while(ch>='0'&&ch<='9'){x=x*10+ch-'0';ch=getchar();} 6 return x*f; 7 }
读入优化(string,char)
1 inline char Getstring() 2 { 3 char s=getchar(); 4 while (s!='i'&&s!='u') s=getchar(); 5 for (char ch=getchar();ch!=' ';ch=getchar()); 6 return s; 7 }
输出优化
