HackerLand Enterprise is adopting a new viral advertising strategy. When they launch a new product, they advertise it to exactly 5 people on social media. On the first day, half of those 5 people (i.e., floor(5/2) = 2) like the advertisement and each shares it with of their friends. At the beginning of the second day, floor(5/2) x 3 = 2 x 3 = 6 people receive the advertisement. Each day, floor(recipients/2) of the recipients like the advertisement and will share it with 3 friends on the following day. Assuming nobody receives the advertisement twice, determine how many people have liked the ad by the end of a given day, beginning with launch day as day 1.A Hacker Rank Problem

# Viral-Adverstising

A Hacker Rank Problem 

HackerLand Enterprise is adopting a new viral advertising strategy. When they launch a new product, they advertise it to exactly 5 people on social media.

On the first day, half of those 5 people (i.e., floor(5/2) = 2) like the advertisement and each shares it with  of their friends. At the beginning of the second day, floor(5/2) x 3 = 2 x 3 = 6 people receive the advertisement.

Each day, floor(recipients/2) of the recipients like the advertisement and will share it with 3 friends on the following day. Assuming nobody receives the advertisement twice, determine how many people have liked the ad by the end of a given day, beginning with launch day as day 1.

## Example

2      6     3       5

3      9     4       9

4     12     6      15

5     18     9      24
