Sum of Array Elements

Given an array of integers nums, return the sum of all elements in the array.

Example 1:

Input: nums = [1, 2, 3, 4, 5]
Output: 15
Explanation: 1 + 2 + 3 + 4 + 5 = 15

Example 2:

Input: nums = [-1, -2, -3]
Output: -6
Explanation: -1 + -2 + -3 = -6

Constraints:

• 1 <= nums.length <= 1000
• -1000 <= nums[i] <= 1000
