Find Anagram Mappings

题目

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] = jmeans 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

P = [1, 4, 3, 2, 0]

asP[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].

思路

题目的意思是B是A序列打乱后的序列，找出A中元素在B中的索引。

遍历A中的元素，再在B中找出他的索引
