Solution: An Array as a Subset of Another Array

Let’s solve the An Array as a Subset of Another Array problem.

We'll cover the following

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:

  • 1≤1 \leq array1.length ≤103\leq 10^{3}
  • 0≤0 \leq array2.length ≤\leq array1.length
  • 10−3≤10^{-3} \leq array1[i] , array2[i] ≤103\leq 10^{3}
  • All the numbers of array1 and array2 are unique
