Data Science can be defined as multidisciplinary blend of trends prediction, data inference, algorithm development, and technology to solve analytically complex problems. At the core of data science is nothing but data.

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.
