Weekends

Given two dates D1 and D2, write a program to count the number of Saturdays and Sundays from D1 to D2 (including D1 and D2).

The date in string format is like "8 Feb 2021".Input

The first line of input will contain date D1 in the string format.

The second line of input will contain date D2 in the string format.Output

The output should be a single line containing two integers separated by space.Explanation

For example, if the given dates are "25 Jan 2021" and "14 Feb 2021", the Saturdays and Sundays dates from "25 Jan 2021" to "14 Feb 2021" are

"30 Jan 2021" is a Saturday

"31 Jan 2021" is a Sunday

"6 Feb 2021" is a Saturday

"7 Feb 2021" is a Sunday

"13 Feb 2021" is a Saturday

"14 Feb 2021" is a Sunday

So the output should be

Saturday: 3

Sunday: 3

Sample Input 1

25 Jan 2021

14 Feb 2021

Sample Output 1

Saturday: 3

Sunday: 3

Write a JAVA program that will compute for the net income of a particular employee. You have to accept name, position, and number of days worked. The position has three categories: if Manager, rate per day is P500; if Supervisor, P400; if Employee, P300. Then after accepting the rate per day, compute gross = rate per day * no. of days worked, compute for the bonus, if gross is >= 8000, bonus = 1000; if gross>= 5000, bonus = 750; if gross >= 3000, bonus = 500; if less, bonus = 0; compute for the deductions: SSS is always 10% of gross; Medicare is always P100; and TAX, if gross >= 7000, tax = 15% of gross; if gross >= 4000, tax = 10% of gross, if gross >=2000, tax = 5% of gross. Then, compute for Net Income = gross + bonus – total deduction. Then, display the net income.
