Minimize Sum Of Array (Array Series #1)

Given an array of integers , Find the minimum sum which is obtained from summing each Two integers product .

Notes

• Array/list will contain positives only .
• Array/list will always has even size

№# Input >> Output Examples

minSum({5,4,2,3}) ==> return (22) 

#№# Explanation:

• The minimum sum obtained from summing each two integers product , 5*2 + 3*4 = 22

minSum({12,6,10,26,3,24}) ==> return (342)

Explanation:

• The minimum sum obtained from summing each two integers product , 26*3 + 24*6 + 12*10 = 342

minSum({9,2,8,7,5,4,0,6}) ==> return (74)

Explanation:

• The minimum sum obtained from summing each two integers product , 9*0 + 8*2 +7*4 +6*5 = 74
