经验教训：数组太小或太大都会WA或TLE或RE
代码：（所有的双等号都要删去其中空格）
#include <stdio.h>
#include <string.h>
char *change(char *a)
{
int len = strlen(a);
if(strchr(a,’.’) != NULL)
{
while(a[–len]= =‘0’);
if(a[len]==’.’)
len–;
a[len+1]=’\0’;
}
return a;
}
int main()
{
char a[50000], b[50000];
while(~scanf("%s %s", a, b))
{
if(!strcmp(change(a),change(b)))
printf(“YES\n”);
else
printf(“NO\n”);
}
return 0;
