    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
