// 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
