/*****************************************************问题描述*************************************************
You are given a string representing an attendance record for a student. The record only contains the following
three characters:
'A' : Absent.
'L' : Late.
'P' : Present.
A student could be rewarded if his attendance record doesn't contain more than one 'A' (absent) or more than
two continuous 'L' (late).
You need to return whether the student could be rewarded according to his attendance record.
Example 1:
Input: "PPALLP"
Output: True
Example 2:
Input: "PPALLL"
Output: False
根据学生的考勤记录判断他是否优秀,多于1个A或存在连续3个或以上的L则返回false
/*****************************************************我的解答*************************************************
/**
* @param {string} s
* @return {boolean}
*/
var checkRecord = function(s) {
var Aarr = s.match(/A/g);
var Larr = s.match(/LLL/g);
return (Aarr == null || Aarr.length < 2) && (Larr == null || Larr.length == 0);
};
console.log(checkRecord("PPALLL"));
