Let s be the subset of the set of ordered pairs of integers defined recursively by basis step is (0, 0)∈ s recursive step: if (a, b) ∈ s, then (a, b+1) ∈ s, (a+1, b+1) ∈ s, and (a+2, b+1) ∈ s what is the list of the elements of s produced by the first four applications of the recursive definition?

step-by-step explanation:

because it just is

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
