How can I give new implementation to methods in String.
For example: I need to give new implementation to concat method, which concats two string and convert to uppercase.
I answered that, i create new custom class and create a method concat and implement it as the way interviewer want, but he asked that he want to do for all the methods in String, so writing new implementation for a methods is not a feasible solution.

There 3 arrays A, B and C, all of equal length. C is the resultant array found using both A and B.

Suppose the size of the array is 3, then we need to find out the following.
c[0] = a[0] * b[1] * b[2]
c[1] = a[1] * b[0] * b[3]
c[2] = a[2] * b[0] * b[2]

I know the answer is pretty easy when it comes to brute force. But the wanted to know the answer with time complexity O(2n) and O(log n)

Note: O(n^2) is not acceptable.
