Virus Outbreak (100 Marks)
In the Martian land faraway, a new virus has evolved and is attacking the individuals at a fast pace. The scientists have figured out the virus composition, V. The big task is to identify the people who are infected. The sample of N people is taken to check if they are POSITIVE or NEGATIVE. A report is generated which provides the current blood composition B of the person.
POSITIVE or NEGATIVE ?
If the blood composition of the person is a subsequence of the virus composition V, then the person is identified as POSITIVE otherwise NEGATIVE.
Example:
Virus Composition, V = coronavirus
Blood Composition of the person , B = ravus
The person in question is POSITIVE as B is the subsequence of the V.
The scientists are busy with their research for medicine and request you to build a program which can quickly figure out if the person is POSITIVE or NEGATIVE. They will provide you with the virus composition V and all the people’s current blood composition. Can you help them?
Note: The virus and blood compositions are lowercase alphabet strings.
