#551 - Student Attendance Record I
Problem Description
You are given a string s representing an attendance record for a student where each character signifies whether the student was absent, late, or present on that day. The record only contains the following three characters:
- 'A': Absent.
- 'L': Late.
- 'P': Present.
The student is eligible for an attendance award if they meet both of the following criteria:
- The student was absent ('A') for strictly fewer than 2 days total.
- The student was never late ('L') for 3 or more consecutive days.
Return true if the student is eligible for an attendance award, or false otherwise.
Solution
/**
* @param {string} s
* @return {boolean}
*/
var checkRecord = function(s) {
return !s.includes('LLL') && (s.indexOf('A') === s.lastIndexOf('A'));
};
