AC代码

#include<stdio.h>
#include<string.h>

char *haha(char *s);

char *haha(char *s){
	while(*s == '0')
		s++;		//去除前导0
	if(strchr(s,'.') != 0){
		int len = strlen(s);
		char *p = s + len- 1;	//指针指向字符串末尾
		while(*p == '0')
			*(p--) = 0;			//去除后导0
		if(*p == '.')
			*p = 0;				//出现1.时把.去掉
	}
	return s;
}

int main(void){
	char a[10000];
	char b[10000];

	while(scanf("%s%s",a,b) != EOF){
		if(strcmp(haha(a),haha(b)) == 0){
			puts("YES");
		}
		else
			puts("NO");
	}
	return 0;
