Compact if statement for Codegolf

[Drew Olson]

I'm working on my codegolfing skills and was wondering, what is the
shortest possible way to write the following in ruby:

if a==0
1
else
2
end

Thanks for the help!

Hi --

I'm working on my codegolfing skills and was wondering, what is the
shortest possible way to write the following in ruby:

if a==0
1
else
2
end

The smallest I can think of is:

a==0?1:2

The smallest I can think of is:

a==0?1:2

if a will only have values 0 or 1 you could use

2**a

if a is always positive you could use

a>0?2:1

cheers.

-a

Hi --

if a will only have values 0 or 1 you could use

2**a

if a is always positive you could use

a>0?2:1

And if a is always 0 you could use:

1

Sorry, couldn't resist

if a will only have values 0 or 1 you could use

2**a

In that case:

a+1

 

[ara.t.howard]

In that case:

a+1

touche techer, touche.

-a

 

[Relm]

if a is always positive you could use

a>0?2:1

or for positive integers

2-0**a

 

[Rajat Garg]

or for positive integers

2-0**a

Very useful
