I need assistance with capitalizing the first character of a string, but only if it is an alphabetic letter. I want to ensure that the remaining characters remain unchanged. Here are some examples of what I’m trying to achieve:
- For the input
“this is a test”
, I expect the output to be“This is a test”
. - Given
“the Eiffel Tower”
, the result should be“The Eiffel Tower”
. - For
“/index.html”
, it should remain“/index.html”
.
