Top Data Science Interview Questions & Answers -- Part 2

For a [1,2,5,7] the least integer not represented by the list or a slice of the list is 4, and if a [1,2,2,5,7] then the least non-representable integer is 18. The answer to these kind of questions is to think logically at different levels. At a fundamental level having more data means additional storage, more computational power and memory requirement. Hence, there is a cost related to more data. Doing a cost to benefit analysis of this scenario can help make an informed decision.
