Give you two numbers A and B, if A is equal to B, you should print "YES", or print "NO".

 

Input

each test case contains two numbers A and B.

 

Output

for each case, if A is equal to B, you should print "YES", or print "NO".

 

Sample Input

1 2

2 2

3 3

4 3

 

Sample Output

NO

YES

YES

NO

 

题解：不需要考虑前置零 把小数点后面多余的 0 去掉再进行比较就可以

 

代码：

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

const int maxn=1e5+10;
char a[maxn],b[maxn];

void rep(char s[]) {
    int len=strlen(s);
    int flag=0;
    for(int i=0;i<len;i++) {
        if(s[i]=='.') {
            flag=1;
            break;
        }
    }
    if(flag) {
        for(int i=len-1;i>=0;i--) {
            if(s[i]=='0') s[i]='';
            else break;
            len--;
        }
        if(s[len-1]=='.') s[len-1]='';
    }
}

int main() {
    while(~scanf("%s%s",a,b)) {
         rep(a);
         rep(b);
      if(strcmp(a,b))
         printf("NO
");
      else
         printf("YES
");
    }
    return 0;
}
