眼看离复赛越来越近了，最近代码打得越来越熟练了，这些是我平时做题必打的代码，在此总结一下
#include<iostream> #include<cstdio> #include<cstring> #include<cmath> #include<cstdlib> #include<algorithm> #include<queue> #include<vector> #include<stack> #include<map> #define R register #define lson l,mid,p<<1 #define rson mid+1,r,p<<1|1 #define next kkksc03 #define gh getchar #define ph putchar using namespace std; typedef long long ll; typedef long double ld; typedef unsigned long long ull; inline ll read(); inline void write(ll x); inline void writeln(ll x); inline void writesp(ll x); inline ll chkmax(ll x,ll y){return x<y?y:x;} inline ll chkmin(ll x,ll y){return x<y?x:y;} inline void chkswap(ll &x,ll &y){R ll t=y;y=x;x=t;} int main(){ } inline ll read(){ ll x=0,t=1;char ch=getchar(); while(ch<'0'||ch>'9'){ if(ch=='-') t=-1; ch=getchar(); } while(ch>='0'&&ch<='9'){ x=(x<<1)+(x<<3)+(ch^48); ch=getchar(); } return x*t; } inline void write(ll x){ if(x<0){ph('-');x=-x;} if(x<=9){ph(x+'0');return;} write(x/10); ph(x%10+'0'); } inline void writeln(ll x){ write(x);ph(' '); } inline void writesp(ll x){ write(x);ph(' '); }
祝2019 CSP-S ++RP，RP++！
