Day 3: Intro to Conditional Statements
Algorithm
input_number=N
Step:-1 First check the input number is even or odd.
Step:-2 if(even(N) AND(N==2 OR 4)) then print("Not Weird");
Step:-3 else if(even(N) AND(N>=6 OR N<=20)) then print("Weird");
Step:-3 else if(even(N) AND (N>20)) then print("Not Weird");
Step:-3 else print("Weird");
Step:-2 if(even(N) AND(N==2 OR 4)) then print("Not Weird");
Step:-3 else if(even(N) AND(N>=6 OR N<=20)) then print("Weird");
Step:-3 else if(even(N) AND (N>20)) then print("Not Weird");
Step:-3 else print("Weird");
Explanation
At first, Check the number is even or odd by using modulo operator(%) and other techniques.If the input_number(N) is odd then directly print out "Weird" and if the input_number is even then there are three condition which are check one by one with the conditional statement.
First condition:- if it is 2 or 4 then print out "Not Weird".
Second Condition:- if it is within the range inclusion 6 to 20 (6<=N<=20) then print out "Weird".
Third Condition:- if it greater than 20 (N>20) then print out "Not Weird".

if(N%2==0 && (N==2 || N==4))
{
System.out.println("Not Weird");
}
else if(N%2==0 && (N>=6 && N<=20))
{
System.out.println("Weird");
}
else if(N%2==0 && N>20)
{
System.out.println("Not Weird");
}
else
{
System.out.println("Weird");
}
scanner.close();
}
