Give me a code to rearrange an array to minimize sum of product of consecutive pair elements and the other steps required given the following:
Rearrange an array to minimize sum of product of consecutive pair elements | Python 3 program to sort an array such that sum of product of alternate element is minimum ..
create evenArr [ ] and oddArr [ ].
sort main array in ascending order.
Put elements in oddArr [ ] and evenArr [ ] as per desired value ..
sort evenArr [ ] in descending order.
merge both sub - array and calculate minimum sum of product of alternate elements.
