Solution: An Array as a Subset of Another Array
Explore how to verify if one array is a subset of another by implementing both brute force and optimized set-based solutions in JavaScript. Understand the importance of time and space complexity in algorithm design and learn how the use of sets can improve lookup efficiency when checking subset relations.
Statement
Given two arrays, array1 and array2, implement a function that takes the two arrays as input and checks whether array2 is a subset of array1.
A subset is a set containing only elements present in another set.
Constraints:
-
array1.length -
array2.lengtharray1.length
