Given two lists Aand 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 ith 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 0th element of A appears at
B[1],
and P[1] = 4 because the 1st element of A appears at
B[4],
and so on.
Note:
A, B have equal lengths in range [1, 100].A[i], B[i] are integers in range [0, 10^5].
