C :

#include <stdio.h>
void main(){
	int n,x,y;
	scanf("%d %d %d",&n,&x,&y);
	int i,j;
	int a = 0;
	for (i=1;i<=n/x;i++){
		for(j=1;j<=n/y;j++){
			if(i*x+j*y==n){
				if(i>=a)
					a=i;
			}
		}
	}
	printf("%d %d",a,(n-a*x)/y);
} 

C++ :

#include <iostream>

using namespace std;

int main(){
	int x,y,n,i,m=0;
	cin>>n>>x>>y;
	for(i=1;i*x<n;i++){
		if((n-i*x)%y==0&&(n-i*x)/y!=0)m=i;
	}
	cout<<m<<" "<<(n-m*x)/y<<endl;
}

Python :

n, x, y = map(int, input().split())
j = []
m = []
for i in range(1, n // x + 1):
    if(n - i * x) > 0 and (n - i * x) % y == 0:
        l = (n - i * x) // y
        j.append(i)
        m.append(l)
        pass
print(max(j), min(m))
