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 <= 1000s[i]is either'A','L', or'P'.
func checkRecord(s string) bool {
absent := 0
late := 0
for i := 0; i < len(s); i++ {
if s[i] == 'A' {
absent++
}
if s[i] == 'L' {
late++
}
if s[i] != 'L' {
late = 0
}
if absent >= 2 || late >= 3 {
return false
}
}
return true
}
