1822 - Sign of the Product of an Array\. Easy There is a function `signFunc(x)` that returns: * `1` if `x` is positive. * `-1` if `x` is negative. * `0` if `x` is equal to `0`. You are given an integer array `nums`. Let `product` be the product of all values in the array `nums`. Return `signFunc(product)`. **Example 1:** **Input:** nums = [-1,-2,-3,-4,3,2,1] **Output:** 1 **Explanation:** The product of all values in the array is 144, and signFunc(144) = 1 **Example 2:** **Input:** nums = [1,5,0,2,-3] **Output:** 0 **Explanation:** The product of all values in the array is 0, and signFunc(0) = 0 **Example 3:** **Input:** nums = [-1,1,-1,1,-1] **Output:** -1 **Explanation:** The product of all values in the array is -1, and signFunc(-1) = -1 **Constraints:** * `1 <= nums.length <= 1000` * `-100 <= nums[i] <= 100`
