1822 - Sign of the Product of an Array.
Easy
There is a function signFunc(x)
that returns:
1
ifx
is positive.-1
ifx
is negative.0
ifx
is equal to0
.
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
