Minimizing the dot product

CodeChefOpen on judge ↗

Abhishek is very good in mathematics. Now he came to know about dot product of vectors. So He asked his friend Suyash a problem. He gave him two vectors A and B of length N . He asked him to minimize the dot product of these two vectors. Suyash has a choice to change the order of the elements of these two vectors i.e. for any two elements i and j in any vector he can interchange the position of th
