Solution: An Array as a Subset of Another Array
Understand how to check if one array is a subset of another by implementing an optimized solution using JavaScript sets. Explore the differences between brute force and hashing approaches, analyze their time and space complexities, and learn how to apply these concepts in coding interview scenarios.
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.length
