2248 - Intersection of Multiple Arrays.

Easy

Given a 2D integer array nums where nums[i] is a non-empty array of distinct positive integers, return the list of integers that are present in each array of nums sorted in ascending order.

Example 1:

Input: nums = [[**3** ,1,2, 4 ,5],[1,2, 3 , 4 ],[3 , 4 ,5,6]]

Output: [3,4]

Explanation:

The only integers present in each of nums[0] = [3 ,1,2, 4 ,5], nums[1] = [1,2, 3 , 4 ], and nums[2] = [3 , 4 ,5,6] are 3 and 4, so we return [3,4].

Example 2:

Input: nums = [[1,2,3],[4,5,6]]

Output: []

Explanation:

There does not exist any integer present both in nums[0] and nums[1], so we return an empty list [].

Constraints:

• 1 <= nums.length <= 1000
• 1 <= sum(nums[i].length) <= 1000
• 1 <= nums[i][j] <= 1000
• All the values of nums[i] are unique.
