Description

Implement an ExamTracker class that supports record(time, score) to log a timed exam score and totalScore(startTime, endTime) to return the sum of all scores logged within the inclusive time interval.

Code

class ExamTracker:

    def __init__(self):
        

    def record(self, time: int, score: int) -> None:
        

    def totalScore(self, startTime: int, endTime: int) -> int:
        


# Your ExamTracker object will be instantiated and called as such:
# obj = ExamTracker()
# obj.record(time,score)
# param_2 = obj.totalScore(startTime,endTime)

class ExamTracker:

    def __init__(self):
        

    def record(self, time: int, score: int) -> None:
        

    def totalScore(self, startTime: int, endTime: int) -> int:
        


# Your ExamTracker object will be instantiated and called as such:
# obj = ExamTracker()
# obj.record(time,score)
# param_2 = obj.totalScore(startTime,endTime)
