551 - Student Attendance Record I.

Easy

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.

Example 1:

Input: s = “PPALLP”

Output: true

Explanation: The student has fewer than 2 absences and was never late 3 or more consecutive days.

Example 2:

Input: s = “PPALLL”

Output: false

Explanation: The student was late 3 consecutive days in the last 3 days, so is not eligible for the award.

Constraints:

  • 1 <= s.length <= 1000
  • s[i] is either 'A', 'L', or 'P'.
