C :

#include <stdio.h>
int main(){
	int n,x,y;
	scanf("%d %d %d",&n,&x,&y);
	int i,j;
	for(i = 1;i <= (n-y) / x;i++){
		j = (n - i * x) / y;
		if(x * i + j * y == n && (n - i * x) % y == 0 && i >= j && i + j >= 5){
			printf("%d %d\n",i,j);
		}
	} 
	return 0;
}

C++ :

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


int main(){
	int n,x,y,i,j,t;
	cin>>n>>x>>y;
	for(i = 1;i <= (n - y) / x;i++){
		//剩余金额
		t = n - i * x;
		//剩余金额可以买三角龙，总数>=5，霸王龙数量>三角龙数量
		if(t % y == 0 && i + t / y >= 5  && i >= t / y){
			cout<<i<<" "<<t / y<<endl;
		} 
	}
	
}

Python :

s = input().split()
n = int(s[0])
x = int(s[1])
y = int(s[2])
for i in range(1, n // x + 1):
    for j in range(1, n // y + 1):
        if x * i + y * j == n and i >= j and (i + j) >= 5:
            print(str(i) + ' ' + str(j))
