Highest Product

Given an array A, of N integers A.

Return the highest product possible by multiplying 3 numbers from the array.

NOTE: Solution will fit in a 32-bit signed integer.

Input Format:

The first and the only argument is an integer array A.

Output Format:

Return the highest possible product.

Constraints:

1 <= N <= 5e5

Example:

Input 1:
A = [1, 2, 3, 4]

Output 1:
24

Explanation 1:
2 * 3 * 4 = 24

Input 2:
A = [0, -1, 3, 100, 70, 50]

Output 2:
350000

Explanation 2:
70 * 50 * 100 = 350000

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
