There is a function signFunc(x) that returns:

\n\n\n\n

You are given an integer array nums. Let product be the product of all values in the array nums.

\n\n

Return signFunc(product).

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [-1,-2,-3,-4,3,2,1]\nOutput: 1\nExplanation: The product of all values in the array is 144, and signFunc(144) = 1\n
\n\n

Example 2:

\n\n
\nInput: nums = [1,5,0,2,-3]\nOutput: 0\nExplanation: The product of all values in the array is 0, and signFunc(0) = 0\n
\n\n

Example 3:

\n\n
\nInput: nums = [-1,1,-1,1,-1]\nOutput: -1\nExplanation: The product of all values in the array is -1, and signFunc(-1) = -1\n
\n\n
