I didn't forget it, it's just not defined as to what I'm supposed to do with 101. My reading of the "constraints" was that the inputs would be between 1 and 100... If the author is now failing you for not taking into account the constraint he should specify what should happen when you're outside the bounds. e.g. throw an exception or print nothing.
Yeah. It is not mentioned what to do if the number is not between 1 and 100. I am getting errors in test case 3 and 7 for my code which is similar to this one. I dont understand what shud be done.
you dont need to add (n%2==0) in
if(n%2==1 || ( (n%2==0) && (n>=6 && n <= 20 ) ) ) statement
as it is not to checking whether the number is even.
we need to check only that number is odd so (n%2==1) is important and number is in bitween 6 to 20.
if this doesnot follow go to direct else statement.
i ran without (n%2==0) statement and it ran perfectly.
are you kidding :-p ,
If n is even and in the inclusive range of 6 to 20, print Weird,
so you didn't check for the even condition and if nis in the range or 6 to 20 you are printing wired, which is wrong
No i agree with you that it should check the even condition but
i dont know what is wrong with the hackerank testing arlgorithm that it is only considering number between 6 to 20(irrespective of even or odd).Go ahead submit the code without n%2==0 condition it does follow all test cases correctly.Thats why i said code is not asking you to check even condition.
Well even I added n%2==0 condition but we do not need to.
As it has been said that if n is odd it is weird and if even numbers between 6-20 are weird then it doesnt matter that the number is even or odd in 6-20 as odd numbers are already weird with the condition n%2==1.
So we can have if(n%2==1 || (n>=6 && n<=20)) for the weird condition.
|| is a short hand operator. If the left side is evaluated to true, it doesnt even evaluate the right side expression. If a number is odd, the right side expression isnt even evaluated - if the number isnt odd, then it must be even right? why bother adding n%2==0 again?
kinda, but I made it this way to get used to this kind of format, since it keeps things organized and, I'm learning java and kinda wanted to experiment a bit on how much "java" I can do on Python. Since Python supports OOP I'm kinda doing everything on a OOP orientation, tho, the dynamic typing doesn't help much.
check the if condition..if the number is odd it will print weird and skip the else part. if the 'if' part proves false then by default the number is even ,it will enter the else loop to check for the limit condition and those numbers might be 6,8,10,12,14,16,18,20

Unless the test cases changed, you don't have to account for input outside the range.

wow i love your reasonning
thanks jangapavanyadav

EXACTLY
You don't need n%2==0. If it's between 6 and 20 inclusive it's Weird. Period. Doesn't matter if it's even or odd.
have you compiled this programme in this website complier?
can you explain
this code is how check the 4 even or odd
worked pefectly!; thanks!!, will study this one more, still a beginner at this.
Can you explain us how you did this in simpler way? Thanks for being super!
The questions says n is even and and between 6 to 20 , by this logic even 7,9,11,13,15,17,19 will print "weird " .? Please expalin .?
you have to print odd numbers as well as even numbers in the range of 6 to 20 as weird. to find the even numbers you have to check if n%2==0
import java.io.; import java.util.;
It is correct.
Tq dude...
I recently joined a java development company, and this was very useful in my daily works. Thanks for sharing.
It is showing error for test case 4. Please help.
String ans=""; --> what's that, please explain
getting error for test case 2: In which for digit 4 error is showing.
can you explain why is so?
import java.util.Scanner; public class Solution {
}
Passed all the tests, could not get right test 7 and 3 by myself...feel dissapointed
Maybe it works, but you make simple program look more complicated. make it simple good luck.

where the second condition the number between 2 to 5 ?
thanks bro...!!
greAT
You have some heavy redundance over there
fine code but no need of checking even condtion at if statment.
If we dont put the constraints, it is not letting us pass the challenge. I dont know how to put constraints for values.
cool
