Probably one hundred million ways. One could be this:


x = "helloha" # => "helloha"
x.capitalize! # => "Helloha"
x[2,1] = x[2,1].capitalize # => "L"


x # => "HeLloha"


And yeah instead of 2,1 you would do 3,1.

Can you explain why those are precisely the ones to capitalize?

Here's one for fun...

SEPARATION, s = 32, 'helloha'
(my_letters = [0, 3]).each {|b| s[b] -= SEPARATION}
puts s

...it's goofy, because I'm golfing and also trying to be descriptive
at the same time :-)

Of course, I'm making a large assumption that the letters to be
capitalized are based on position.

Here's a contrived one...

include 'matrix'
(Vector[*'helloha'.unpack('C*')] - Vector[1,0,0,1,0,0,0] * 32).to_a.pack('C*')

...umm, ugly.

Hi Li,

irb(main):016:0> a="HelLoha"
=> "HelLoha"
irb(main):017:0> a.downcase
=> "helloha"
irb(main):018:0>

So simply reversible

irb(main):016:0> a="HelLoha"
=> "HelLoha"
irb(main):017:0> a.downcase
=> "helloha"
irb(main):018:0> a="helloha"
=> "helloha"
irb(main):019:0> a=a.capitalize!
=> "Helloha"
irb(main):020:0> a=a[0,3]+a[3,1].capitalize!+a[4,3]
=> "HelLoha"
irb(main):021:0>

There must be a language barrier. I thought the point was to turn
'helloha' _into_ 'HelLoha', and not the reverse.

Well, you might be right with your first post, since you never know
what the original poster meant. Not everyone, after all, has a
command of the english language. And that would include me, lol.
