Biological Motivation

Klonopin works by enhancing the activity of certain neurotransmitters in the brain. 0.25 mg twice daily is a typical starting dose. An increased dose is the dose of 0.5 mg, taken twice daily after three days. The maximum daily dose is 4 mg. Dose reduction: When discontinuing treatment with this drug, a doctor should gradually reduce a person's dose. They should reduce the dose every three days by no more than 0.125 mg. For example, if the person was taking 2 mg twice daily, their doctor would first reduce the dose to 1.875 mg twice daily.

Return: Four integers corresponding to the number of times that the symbols A, C, G, and T occur in $s$.
