Question

Define minial pairs product sum?​

Answer 1

Answer:

Write a function that receives an array of integers and returns the minimal sum of the array (sum of products of each two adjacent numbers).

For Example:

Without sorting the array [40,25,10,5,1], the sum is:

(40*25) + (25*10) + (10*5) + (5*1) = 1305
