Solution: An Array as a Subset of Another Array
Explore how to determine if one array is a subset of another by using hashing techniques in C#. Learn to implement both a brute force and a set-based optimized method to solve this common coding interview problem efficiently. Understand the time and space complexity trade-offs involved with each approach.
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
