Solution: An Array as a Subset of Another Array
Explore how to verify if an array is a subset of another by implementing and comparing a brute force method with an optimized approach using sets. Understand the time and space complexities behind these techniques to write more efficient C++ code.
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
