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”

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.

class String
def capitalize_at(*indices)
str = self.dup
indices.each do |i|
if chr = self[i, 1]
str[i,1] = chr.upcase
else
raise IndexError.new(“character #{i} out of index”)
end
end
str
end
end
“helloha”.capitalize_at(0, 3) # => “HelLoha”
If you find yourself doing it frequently.
There must be a language barrier.
Isn’t it, after all, the “natural” languages which separate us all
mostly, while Ruby unites our thinking brains …
Cheyne Li, Ruben’s example is probably the best if you think you need
to do this more often. Ruby by default has .capitalize already, so I’d
guess a .capitalize_at method seems like a good name.

Thank you very much. It helps a lot
