n. leader
misc. leader character ; leading character
如果前导字符长度太长，与整个区域明显不适应，那么它将会令起一行。
If the leader's length is too long to fit in the area, the leader will begin a new line.
由于这个结果保存在一个整数变量中，因此，显示值的消息应该使用一个格式化代码，为代码填充具有前导零的四个字符。该代码数量不到1000个。
Because this result is held in an integer variable, a message to display the value should use a formatting code to pad to four characters with leading zeros for codes that are numbered less than 1000.
因此，我要用前导零填充其余比赛，为所有比赛赋相同数量的字符。
So I'll just pad the remaining RACES with leading zeros, giving all RACES the same number of characters.
