思路：把小数点后面的多余的零去掉，同时注意如果最后一位是小数点的话，也要去掉，（就在这里wa了好多次）

上代码：

#include<cstdio>
#include<cstring>
#include<iostream>
#include<algorithm>
using namespace std;
const int maxn = 1e6+5;
char a[maxn],b[maxn];
int qSpot(char *c,int lenn){
	int len = lenn,len1 = lenn;
	for(int i = 0;i<len;i++){
		if(c[i]=='.'){
			len = i;
			break;
		}
	}
	int s = 0;
	for(int i = len1-1;i>=len;i--){
		if(c[i]=='0'){
			s++;
		}
		else{
			break;
		}
	}
	if(c[len1-s-1] == '.') s++;
	return len1 - s;
}
int main()
{
	while(~scanf("%s %s",a,b)){
		int len = strlen(a);
		int len1 = strlen(b);
		len = qSpot(a,len);
		len1 = qSpot(b,len1);
		//printf("%d %d
",len,len1);
		if(len != len1) printf("NO
");
		else{
			bool falg = true;
			for(int i = 0;i<len;i++){
				if(a[i]!=b[i]){
					falg = false;
				}
				if(falg == false) break;
			}
			if(falg) printf("YES
");
			else printf("NO
");
		}
	}
	return 0;
 }
