Hospital Simulator

You were asked by a doctor friend to prepare for her a “Hospital simulator”, which can simulate the future patients’ state, based on their current state and a list of drugs they take. Patients can have one of these states:

• F: Fever
• H: Healthy
• D: Diabetes
• T: Tuberculosis
• X: Dead

In the “Hospital simulator” drugs are provided to all patients. It is not possible to target a specific patient. This is the list of available drugs:

• As: Aspirin
• An: Antibiotic
• I: Insulin
• P: Paracetamol

Drugs can change patients’ states. They can cure, cause side effects or even kill a patient if not properly prescribed. Drugs effects are described by the following rules:

• Aspirin cures Fever;
• Antibiotic cures Tuberculosis;
• Insulin prevents diabetic subject from dying, does not cure Diabetes;
• If insulin is mixed with antibiotic, healthy people catch Fever;
• Paracetamol cures Fever;
• Paracetamol kills subject if mixed with aspirin;

Input

Parameter 1

• List of patients' health status codes, separated by a comma. e.g. “D,F,F” means we have 3 patients, one with diabetes and two with fever.

Parameter 2

• List of drugs codes, separated by a comma, e.g. “As,I” means patients will be treated with Aspirin and Insulin.

Output

The result should be sent to stdout.

It should be a comma separated string with number of patients with a given state, following the format:

F:NP,H:NP,D:NP,T:NP,X:NP

Where:

• F, H, D, T, X are patients’ health status codes;
• NP is a number of patients for a given state;
• E.g. “F:0,H:2,D:0,T:0,X:1” means there are two healthy patients and one that is dead.

Examples

Example 1

• Input: “F,D,T,T”
• Output: “F:0,H:0,D:0,T:0,X:2” (diabetic patients die without insulin)
• $ java -jar hospitalSimulatorProject-1.0-SNAPSHOT.jar "F,D,T,T" "P,An,I"
• F:1,H:0,D:0,T:2,X:1

Example 2

• Input: “F” “P”
• Output: “F:0,H:1,D:0,T:0,X:0” (paracetamol cures fever)
• $java -jar hospitalSimulatorProject-1.0-SNAPSHOT.jar F P
• F:0,H:1,D:0,T:0,X:0
