Medium

Database

Problem Explanation

Explanation

To solve this problem, we need to count the number of tasks that fall on weekends in a given range of dates. We can achieve this by iterating over the range of dates and checking if each date falls on a weekend (Saturday or Sunday).

Iterate over the range of dates.
Check if the current date is a Saturday or Sunday.
If the current date is a weekend, increment the tasks count.

Time Complexity

The time complexity of this solution is O(n), where n is the number of days in the given range.

Space Complexity

The space complexity of this solution is O(1) as we are not using any extra space that grows with the input size.

Solution Code

public int countWeekendTasks(int startDay, int startMonth, int startYear, int endDay, int endMonth, int endYear) {
    int count = 0;
    LocalDate startDate = LocalDate.of(startYear, startMonth, startDay);
    LocalDate endDate = LocalDate.of(endYear, endMonth, endDay);

    while (!startDate.isAfter(endDate)) {
        if (startDate.getDayOfWeek() == DayOfWeek.SATURDAY || startDate.getDayOfWeek() == DayOfWeek.SUNDAY) {
            count++;
        }
        startDate = startDate.plusDays(1);
    }

    return count;
}
