Count Level 1 Markdown Headers

Markdown is a lightweight markup language. In Markdown, if the first non‐whitespace character of a line is a hash sign (#) and it is immediately followed by one or more space characters, then the remaining non‐whitespace content of that line is rendered as a level 1 title.

More formally, let a line (after removing leading whitespace) be denoted as S. Then S represents a level 1 title if and only if:

• S[0] == '#' (i.e. the first character is a hash),
• The character immediately following '#' is a space (i.e. S[1] == ' '),
• There exists at least one non‐space character after the consecutive spaces.

Note that lines such as "## This is a secondary title" or "#You should insert a space" do not qualify as level 1 titles.
