什么叫多项式!!!1002. A+B for Polynomials (25)

坑嗲啊,这么简单的问题!!

多项式只有一个未知数有没有!

靠,,,

谁出的题,坑爹。。

#include<stdio.h>
#include<string.h>
#include<algorithm>
using namespace std;
int main(){
	int k,e;
	double c;
	double a[10010];
	int ans = 0;
//	memset(v,0,sizeof(v));
	memset(a,0,sizeof(a));
	scanf("%d",&k);
	while(k--){
		scanf("%d%lf",&e,&c);
		a[e]+=c;

	}
	scanf("%d",&k);
	while(k--){
		scanf("%d%lf",&e,&c);
		a[e]+=c;
	}
	for(int i = 10009;i>=0;i--){
		if(a[i])ans++;
	}
	printf("%d",ans);
	for(int i = 10009;i>=0;i--){
		if(a[i]){
			printf(" %d %.1f",i,a[i]);
		}
	}
	puts("");
	return 0;
}
