Get first letter

Patterns

Applicable neurons

• 0
• 1
• Substring (from start to position)
• Substring (from position to end)
• Get after substring
• NOR
• Degrees into radians
• 3 digits of ascii code into character
• √¯(x² - y²)
• [a, b]
• String can contains only characters, digits, space
• select .... order by .... asc (A, B, C)
