What is the time complexity of the given approach?

O(m log m + n log n)

O(m + n)

O(m * log n)

O(m * n) (correct)

What is the space complexity of the given approach?

O(1)

O(max(m, n))

O(m * n)

O(m + n) (correct)

What is the purpose of the 'if' condition in the forEach loop?

To check if the element is present in arr2

To check if the element is present in arr1

To check if the element is present in either of the arrays

To check if the element is present in both arrays and is unique (correct)

Given two arrays, find the intersection(items occur in both arrays)

arrays are not sorted, and might have duplicates. you can modify the arrays you can return the items in any order, but without duplicates. This is an easy problem, What is the time & space complexity of your approach?
