25. Reorder array with new indexes
Share
easy - accepted / - tried
Suppose we have an array of items - A
, and another array of indexes in numbers - B
const A = ['A', 'B', 'C', 'D', 'E', 'F']const B = [1, 5, 4, 3, 2, 0]
You need to reorder A, so that the A[i] is put at index of B[i], which means B is the new index for each item of A.
For above example A should be modified inline to following
['F', 'A', 'E', 'D', 'C', 'B']
The input are always valid.

It is fairly easy to do this by using extra O(n)
space, could you solve it with O(1)
space?
