In Python is very simple

Example

age = int(19)
txt = str("Hello my name is Beno, i'am {} years old")
print(txt.format(age))

Added const for the char* r

That's just a formatting preference. What's I think is a bad formatting preference is putting anything after a scope-closing } on the same line.

Just a minor Feedback:
if you're using the curlybrackets, then put them in the next row so the code is simpler to read.

petty mid

char fanis(char r, int k) {
for (; *r; *r++)
*r = k + *r;
return r;
}

This is brainfuck not python for babies

Been a very long time since I touched this, but it's string comparison to see if one string can be transformed into a second string only by adding, removing or swapping a single character.

With that said, we were apparently code golfing and optimizing performance just for fun, you should absolutely not take this code as a good example of well-written Ruby.

Less lines != good code

What is the actual purpose of "One Away"?.

To compare a pair of ranges, strings or arrays?.

Would appreciate some comments.

Many regards,

Maybe change the function nameto follow best practise, like equal_sum?.

:o i can do that???

how about:

unwords . fmap ((l:ls) -> toUpper l : ls) . words

fails for n = 99999999999999999

I think your previous solution was more efficient, this one keesp repeatedly searching the lowerbound, the prior compared as interleaving
