	return 0;
}

求赞

#include<bits/stdc++.h>
const int N=1e5+10;
using namespace std;
int main(){
	int a,b,c;//a表示跳绳数，b表示减去数
	cin>>a>>c;
	if(a%c==0){
		cout<<a/c;
	}
	if(a%c!=0){
		b=a%c;
		a=a-b;
		cout<<b<<" "<<a/c;
	}
	if(a==0&&b==0)
		cout<<"0";
	return 0;
}

然后，你错了😄

先用数学的方式理解

#include <stack>
#include <iostream>
#include <iomanip>
#include <string.h>
#include <algorithm>
using namespace std;
int main() 
{
    int n,m,a,b,c;
    cin>>n>>m;
    a=n/m;
    c=a*m;
    b=n-c;
    cout<<b<<" "<<a;
}

#include <stdio.h>

#include <iostream>

using namespace std;

int main()

{

int a,b;

cin>> a >> b ;

cout<< a % b << " " << (a - a % b) /b;

}

#include <stack>
#include <iostream>
#include <iomanip>
#include <string.h>
#include <algorithm>
using namespace std;

int main() {
int n,m,a,b,c;
cin>>n>>m;
a=n/m;
c=a*m;
b=n-c;
cout<<b<<" "<<a;
}
