A == B?

首先我处理了前导的0;

        while( *p1 == '0' )
               p1++;
           while( *p2 == '0' )
               p2++;

用了指针移动指向来实现的。

然后处理了“.”号, 因为在小数中,一个小数点,后面什么也没有,可以。所以我讲小数点置为空。

if( *p1 == '.' )   *p1 = 0;

而且处理了后导0, 就使后面所以的0 都置为空,就相当于没有。

最后比较就可以了~~

Problem Description
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

6 {
7 int len = strlen( p );
8 char *p1 = p + len - 1;
9 if( strchr( p, '.' ) )
10 while( *p1 == '0' ) *p1-- = 0;
