Build an optimized algorithm.

Prefer Javascript or C/C++ language.

Please don't spend more than 1-2 hours on this. Show us your best coding & documentation style - the way you like to write code.

You are given a list of integers, both positive and negative. Each integer in the list must either be paired with another element in the list or be a single element. Once the elements have been paired, the integers in the pairs are multiplied and the results are summed up - the sum will include the single elements.

Write a program to find the biggest possible sum.

Examples:

for the list [0,1,2,3,4,5] the pairs (4,5) and (2,3) are formed and 0 and 1 are single elements. The max. sum is 27 - (20+6+0+1).

for the list [-1,0,1] the pairs (-1,0) is formed and 1 is a single element. The max. sum is 1.

for the list [1,1] no pairs are formed only two single elements. The max. sum is 2. You choose the implementation language and how input/output is handled etc.

A simple optimal algorithm in linear time O(n) for sorted array or O(n*log(n)) for unsorted. It was tested for millions of generated cases by comparing with a slow but reliable reference algorithm.

Lets look at sequence of four different positive numbers sorted from least to the greates value - m1,m2,m3,m4. It can be proved that greatest sum is m3*m4+m1*m2, i.e. it is bigger than other combinations. That suggest Flere
