Solution: An Array as a Subset of Another Array
Explore how to check if one array is a subset of another using hashing. Understand both brute force and optimized map-based approaches with clear code examples and complexity analysis. This lesson helps you apply efficient data structures to solve subset problems in Go 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.length
