23 December,Happy Farmers Day!

The National Farmers Day in India is also known as Kisan Divas in Hindi.

Farmer's Day is celebrated every year on 23 December,
on the birthday of the 5th Prime Minister of India,
Choudhary Charan Singh, also a farmer's leader,
who introduced many policies to improve the lives of the Indian farmers.


It is celebrated by organizing various programs, debates, seminars, quiz competitions, discussions, workshops, exhibitions, essays writing competitions and functions.

Farmers are backbone of a country and you can’t stand straight if your backbone is broken.
The life of a farmer is very tough as he works very hard day and night in all seasons for us.
Happy Farmers Day!

National Mathematics Day.

The Indian government declared 22 December to be National Mathematics Day. This was announced by Prime Minister Manmohan Singh on 26 February 2012 at Madras University, during the inaugural ceremony of the celebrations to mark the 125th anniversary of the birth of the Indian mathematical genius Srinivasa Ramanujan (22 Dec 1887 -26 Apr 1920). On this occasion Singh also announced that 2012 would be celebrated as the National Mathematics Year.

Srinivasa Iyengar Ramanujan was born on December 22, 1887 in the present day Tamil Nadu, India. He is one of the most recognised Indian mathematicians although he had almost no formal training in pure mathematics. He is known for mathematical analysis, number theory, infinite series, and continued fractions, including solutions to mathematical problems considered to be unsolvable.

Write a python program to check if the number is an Armstrong number or not take input from the user

Write a python program to check if the number is an Armstrong number or not take input from the user

num = int(input("Enter a number: "))
# initialize sum
sum = 0
# find the sum of the cube of each digit
temp = num
while temp > 0:
   digit = temp % 10
   sum += digit ** 3
   temp //= 10
# display the result
if num == sum:
   print(num,"is an Armstrong number")
else:
   print(num,"is not an Armstrong number")

Output:

Enter a number: 407
407 is an Armstrong number

Java Program to Check a Leap Year

Java Program to Check a Leap Year:

public class LeapYear {
    public static void main(String[] args) {
        int year = 1900;
        boolean leap = false;
        if(year % 4 == 0)
        {
            if( year % 100 == 0)
            {
                // year is divisible by 400, hence the year is a leap year
                if ( year % 400 == 0)
                    leap = true;
                else
                    leap = false;

            System.out.println(year + " is a leap year.");
        else
            System.out.println(year + " is not a leap year.");
    }
}

Output:
2020 is a leap year.
