760. Find Anagram Mappings

Given two lists A and B , and B is an anagram of A . B is an anagram of A means B is made by randomizing the order of the elements in A .

We want to find an index mapping P , from A to B . A mapping P[i] = j means the i th element in A appears in B at index j .

These lists A and B may contain duplicates. If there are multiple answers, output any of them.

For example, given

A = [12, 28, 46, 32, 50]
B = [50, 12, 32, 46, 28]

We should return
[1, 4, 3, 2, 0]
as P[0] = 1 because the 0 th element of A appears at B[1] , and P[1] = 4 because the 1 st element of A appears at B[4] , and so on.

Note:

  1. A, B have equal lengths in range [1, 100] .
  2. A[i], B[i] are integers in range [0, 10^5] .
