@[璀璨星空1](/space/show?uid=130897) orz这不是个贪心的例题吗

是不是我算法的问题？
~~我用的递归~~

# 请勿抄
```cpp
#include<bits/stdc++.h>
const int X=250;
const char ERR=' ';
char a[X+5];
int n,del,h;
void cross(int sta,int end,int num)
{
int l=0,mnw=127,mnp;
for(int i=sta;i<=end;i++)
if(a[i]!=ERR)
l++;
if(num==0)
return;
else if(num==l)
{
for(int i=sta;i<=end;i++)
a[i]=ERR;
return;
}
else
{
for(int i=sta;i<=sta+num;i++)
{
if(a[i]==ERR)
continue;
if(a[i]<mnw)
mnw=a[i],mnp=i;
}
if(mnp==1)
cross(sta+1,end,num);
else
{
int t=0;
for(int i=sta;i<mnp;i++)
a[i]=ERR,t++;
cross(mnp+1,end,num-t);
}
}
return;
}
void SOLVE()
{
scanf("%s%d",(a+1),&del);

for(int i=1;i<=n;i++)

if(a[i]!='0'&&a[i]!=ERR) h=1;
if((h||i==n)&&(a[i]!=ERR)) printf("%c",a[i]);
}
printf("\n");

@[璀璨星空1](/space/show?uid=130897) 递归也是普及-啊。

```
#include<bits/stdc++.h>
using namespace std;
int s;
string n;
#define re register int

cin>>n>>s;
int len=n.length();
for(re i=1;i<=s;i++,len--)
for(re j=0;j<=len-1;j++)
if(n[j]>n[j+1])

break;
}
re p=0;
while(n[p]=='0') p++;

emmm
~~咋这么长~~
```
#include<stdio.h>
char s[10000002];
int k;
int main(){
scanf("%s%d",s,&k);
int i=0,j=1;
while(s[j-1]!=0){
if(k<=0||s[i]<=s[j])s[++i]=s[j++];
else{
i--;k--;
}
}
for(i=0;s[i]=='0';i++);
printf("%s\n",s+i);
}
```

泥萌怎么定义的普及+啊
普及+应该和今年普及T4差不多吧

额
额额
额额额
额额额额
额额额额额

```
for(;;printf("额");)
