All positive solutions, including zero:
2x - 1 < 3
2x < 4
x < 2
solutions (integers): 0 and 1
All negative solutions:
2x - 1 < -3
2x < -2
x < -1
Since the question is asking you for solutions that are non-negative integers, the answer is 0 and 1.
The building of a hacker rank is one that cost a lot of money and as such the minimum cost is 4.
