In this post, we will solve Databases – Natural Joins HackerRank Solution. This problem (Databases – Natural Joins) is a part of HackerRank Databases series.
Task
Relation R(A,C) has the following tuples:
A : C
3,3
16,4
12,3
3,15
27,1
Relation S(B,C,D) has the following tuples:
B : C : D
50,1,6
1,55,8
4,3,9
The following tuple is in the result of the natural join between R and S where tuples are structured as (A,B,C,D):
27, X, Y, Z
In the answer box, fill up the values of the integers X, Y and Z in three separate lines. e.g.
10
20
