• Character

• Yes / No

## Neuron type

Best algorithm has been found - locked

## Patterns

Pattern Input Output

 Character: A
 Yes / No: 1
2.
 Character: B
 Yes / No: 1
3.
 Character: v

• IF (1) THEN a ELSE b
• Sum of complex numbers
• Quadratic equation (ax² + bx + c = 0)
• character v
• Calculate VAT
• after decimal point
• word largest
• null
• character u
• get hours from time (hh:mm:ss)
