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 Java. Understand the associated time and space complexities and improve your algorithm efficiency for coding interviews.
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
