江西 2022 CSP-J/S 奇葩代码合集

zaochen · 2022-10-29 21:56:26 · 休闲·娱乐

手翻。持续更新中。由于我是 J 组所以先更新 J 组的。

若发现你的代码被选中但是不想被公开可以私信我撤一下，也欢迎大家来认领代码。

总览：JX的J组280个参赛OIers总共写了1277个#include,159个iostream,38个cmath,875个万能头,44个#define int long long,14个rand(),4个114514
454个'//',3个ccf,本次JX的J组选手十分文明，代码中没有出现"f**k"

1.喜报：//freopen
大概有69个freopen被注释掉

  //freopen("decode.in", "r", stdin);
  //freopen("decode.out", "w", stdout);

signed main() {
  //int n, k;

  cin >> n >> k;
  for (int i = 1; i <= n; ++ i) {
    cin >> P[i].x >> P[i].y;
  }
  Get(1);
  cout << ans << '\n';
  return 0;
}

2.cmath 人

#include <bits/stdc++.h>
using namespace std;
int main()
{
    freopen("pow.in","r",stdin);
    freopen("pow.out","w",stdout);
   int a,b;
   cin>>a>>b;
   if(pow(a,b)>pow(10,9))
   {
      cout<<"-1";
   }
   else
    {
        cout<<pow(a,b);
    }

    return 0;
}

还有好多
3.No 人
T2是"NO"而不是"No"，而JX-J00003的T2:

if(p[i]==0)
{
  cout<<"No"<<endl;
}

4.张冠李戴人
JX-J00003的T3：

    freopen("pow.in","r",stdin);
    freopen("pow.out","w",stdout);

5.打表人
T3居然能打表，这是我没有想到的，但JX-J00004做到了.

cin>>s;
if(s.size()==1) cout<<s[0]<<endl<<0<<" "<<0;
if(s.size()==3){
    if(s[1]=='&'){
        if(s[0]=='0') cout<<0<<endl<<1<<" "<<0;
        else if(s[2]=='0') cout<<0<<endl<<0<<" "<<0;
        else cout<<1<<endl<<0<<" "<<0;
    }
    if(s[1]=='|'){
        if(s[0]=='1') cout<<1<<endl<<0<<" "<<1;
        else if(s[2]=='1') cout<<1<<endl<<0<<" "<<0;
        else cout<<0<<endl<<0<<" "<<0;
    }
}

6.(10,9)人
JX-J00005的T1:

if(n<(10,9))

7.样例人
JX-J00008的T3：

string u="(((((1&(0&0|1))...

8.天命打表人
就当我认为打表人很厉害时，我看到了JX-J00008

if(s.size()>5)
    {
        srand(unsigned(0));
        cout<<rand()%2<<endl;
        cout<<rand()%(s.size()/5)<<" "<<rand()%(s.size()/7)+1;
        return 0;
    }
...后接打表

9.bool值是2人
JX-J00010的T3，在经过一通我不理解的计算后，得到了bool值是2

#include<bits/stdc++.h>
using namespace std;
int main(){
  freopen("expr.in","r",stdin);
  freopen("expr.out","w",stdout);
  string s;
  cin>>s;
  lens=s.size();
  for(int i=1;i<=lens;i++){
    if(s[i]=='0'){
      az++;}
    if(s[i]=='1'){
      ax++;}
  }
  if(ax>az){
    cout<<1<<endl;}
  if(az%2==0){
    cout<<2<<endl;}
  cout<<1<<" "<<ax-az;
  return 0;
}

10.6人
JX-J00012的T4，单走一个6，没写freopen...

#include <iostream>
#include <cstdio>
using namespace std;
int main()
{
 cout<<6;
 return 0;
}

这是他的 T3:

#include <bits/stdc++.h>
using namespace std;
int ans;
string a;
long long ;
int main()
{
 cout<<1<<endl;
 cout<<3<<" "<<3;
 return 0;
}

11.in main 人

#include<iostream>
using namespace std;
in main(){
    freopen("pow.in""r",stdin);
    freopen("pow.out""w",stdout);
    int a,b,sum=1;
    cin>>a>>b;
    for(int i=0;i<=b;i++){

        sum=sum*a;
        i++;
        }
    for(int i=0;i<=b;i++){
        if(sum<1000000000)cout<<sum<<endl;
        else return -1;
    }
    return 0;
}

12.freopen 垫底人
JX-J00014的每道题,都...

#include<bits/stdc++.h>
using namespace std;
struct jm{
    int n,e,d,p,q;
}a[100005];
int main()
{
    int k;
    cin>>k;
    for(int i=0;i<k;i++){
        cin>>a[i].n>>a[i].e>>a[i].d;
    }
    for(int i=0;i<k;i++){

    }
    for(int i=0;i<k;i++){
        if(a[i].p<a[i].q){
            cout<<a[i].p<<" "<<a[i].q<<endl;
        }
        else{
            cout<<a[i].q<<" "<<a[i].p<<endl;
        }
    }
    freopen("decode.in","r",stdin);
    freopen("decode.out","w",stdout);
    return 0;
}

13.写了freopen但是仍然爆零人
JX-J00016每题都写了freopen

freopen("decode","in","r","stdin");
freopen("decode","out","w","stdout");

14.ccf lover

/*
CCF I love you!!!
 */

//love CCF

15.打表打错人

#include <bits/stdc++.h>
using namespace std;
int main(){
    freopen("expr.in","r",stdin);
    freopen("expr.out","w",stdout);
    long long n;
    cin>>n;
    if (n=0&(1|0)|(1|1|1&0)){
        cout<<n<<endl<<"1 2";
    }
    if (n=(0|1&0|1|1|(1|1))&(0&1&(1|0)|0|1|0)&0){
        cout<<n<<endl<<"2 3";
    }
    if (n=(0|1&0|1|1|(1|1))&(0&1&(1|0)|0|1|0)&0){
        cout<<n<<endl<<"2 3";
    }
    else{
        cout<<"0"<<endl<<"13574 23148";
    }

    return 0;
}

16.又是freopen

freopen("decode.cpp",r,"decode.in");
freopen("decode.cpp",w,"decode.out");

17.表白人
JX-J00026和JX-J00027两人，代码的注释中都出现了...
然而这两位考生，一个初三，一个初二...
JX-J00026:

//cout << "My dear xkx I love you!!!" << endl;

JX-J00027:

//I love Juliet for ever.

18.a^b人

JX-J00028的T1使用了^计算乘方，不知是在写c++还是excel:

#include<iostream>
using namespace std;
int main(){
freopen("pow.in","w"stdin)
freopen("pow.out","r"stdout)
    long long a,b;
    long long n;
    cin>>a>>b;
    n=a^b;
    while(n<1000000000){
        cout<<n;
    if(n>1000000000)
        cout<<"-1";
    return 0;
    }
}

另外，此人的T2,T3,T4提交了相同的代码

#include<iostream>
using namespace std;
int main(){
freopen("decode.in","w"stdin)
freopen("decode.out","r"stdout)
return 0;

19.二分人
JX-J00029使用二分解决数学题T2:

while(l<=r){
            ull p=(l+r)/2;
            if(p*(n-m+2-p)>n)r=p-1;
            else if(p*(n-m+2-p)==n&&n%p==0){
                cout<<min(p,n/p)<<" "<<max(p,n/p)<<endl;
                b=0;
                break;
            }
            else l=p+1;
        }

20.长注释人
JX-J00030的T3有一个长长的注释，和一段打表代码

/*
#include<bits/stdc++.h>
using namespace std;

struct lian{
    int next,last,val;
};

string s;
int ans,nex;

bool dfs(int p) {
    vector<lian> v;
    for(int i=p;i<s.length()&&s[i]!=')';i++) {
        if(s[i]==')') {
            nex=i+1;
            for(int i=1;i<v.size();++i) {
                if(v[i].val==2) {
                    v[i].val=v[v[i].last].val|v[v[i].next].val;
                    v[v[i].last].val=-1;
                    v[v[i].next].val=-1;
                    v[i].last=v[v[i].last].last;
                    v[i].next=v[v[i].next].next;
                    v[v[i].last].next=v[i].next;
                    v[v[i].next].last=v[i].last;
                }
            }
            for(int i=1;i<v.size();++i) {
                if(v[i].val==3) {
                    v[i].val=v[v[i].last].val&v[v[i].next].val;
                    v[v[i].last].val=-1;
                    v[v[i].next].val=-1;
                    v[i].last=v[v[i].last].last;
                    v[i].next=v[v[i].next].next;
                    v[v[i].last].next=v[i].next;
                    v[v[i].next].last=v[i].last;
                }
            }
            for(int i=1;i<v.size();++i) {
                if(v[i].val>-1) {
                    return v[i].val;
                }
            }
        }
        if(s[i]=='0') v.push_back({i-1,0,i+1});
        else if(s[i]=='1') v.push_back({i-1,1,i+1});
        else if(s[i]=='|') v.push_back({i-1,2,i+1});
        else if(s[i]=='&') v.push_back({i-1,3,i+1});
        else if(s[i]=='(') {
            v.push_back({i-1,dfs(i+1),i+1});
            i=nex;
        }
    }
}

int main() {
    cin >> s;
    cout << dfs(0) << endl;
    return 0;
}
*/

#include<iostream>
using namespace std;

string s;

int main() {
    freopen("expr.in","r",stdin);
    freopen("expr.out","w",stdout);
    cin >> s;
    if(s.length()<=3) {
        if(s=="1|1" || s=="1|0") {
            cout << 1 << endl;
            cout << 0 << ' ' << 1;
        }else if(s=="0|1") {
            cout << 1 << endl;
            cout << 0 << ' ' << 0;
        }else if(s=="0|0") {
            cout << 0 << endl;
            cout << 0 << ' ' << 0;
        }else if(s=="1&1") {
            cout << 1 << endl;
            cout << 0 << ' ' << 0;
        }else if(s=="0|1" || s=="0|0") {
            cout << 0 << endl;
            cout << 0 << ' ' << 1;
        }else if(s=="1&0") {
            cout << 0 << endl;
            cout << 0 << ' ' << 0;
        }
    }else {
        cout << 1 << endl;
        cout << 1 << ' ' << 1;
    }
    fclose(stdin);
    fclose(stdout);
    return 0;
}

另外，此人的T1题最后有一段长长的注释

21.爆零人
JX-J00031的每题都没写freopen,在此点名表扬

22.dp人

//ccf ni kao zhe wan yi?wo fu xi le yi zhou DP ni yi ti dou bu kao?

23.wryyy

  //wryyy think this problem is also /\ hard
  //wryyy's horse bee is very ugly
  //wryyy don't like zifuchuan and moni

24.万能头人
JX-J00101和JX-J00229的万能头，分别叫 <bits/stdc++> 和 <bits/stdc++>h>

25.??? 人
JX-J00248的T4只有3行，但是

#include <fstream>
#include <memory>
inline int* __(void* pt,register uint_least16_t* ptm,uint64_t*** ptg){*ptm=0x57;delete ptg;return nullptr;}int main(){std::wifstream input{};input.open("point.in");std::wofstream output{};output.open("point.out");for(;;)delete[] __(nullptr,nullptr,nullptr);}

26.基督教信徒
JX-J00279的每题中注释都有
