First n Items

You get a vector of integers nums and a number n. Return a vector with the first n numbers of nums.

Keep them in the same order. When n is 0, return an empty vector.

Example 1:

Input: nums = [3, 8, 1, 9, 4], n = 3
Output: [3, 8, 1]
Explanation: The first 3 numbers are 3, 8 and 1.
The 9 and the 4 are left out.

Example 2:

Input: nums = [5, 6, 7], n = 0
Output: []
Explanation: No numbers are taken, so the result is empty.

Example 3:

Input: nums = [2, 4], n = 2
Output: [2, 4]
Explanation: n is the length of nums, so every number is kept.

Constraints:

• nums has 1 to 10 numbers.
• Every number is an integer from -1000 to 1000.
• n is from 0 to the length of nums.
