From 2e8cc76a62aca89c89043440a47191e9c939a8e2 Mon Sep 17 00:00:00 2001 From: Sukeysun <578108683@qq.com> Date: Wed, 9 May 2018 09:38:31 +0800 Subject: [PATCH] Add files via upload 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]. --- Find Anagram Mappings.py | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 Find Anagram Mappings.py diff --git a/Find Anagram Mappings.py b/Find Anagram Mappings.py new file mode 100644 index 0000000..87e9116 --- /dev/null +++ b/Find Anagram Mappings.py @@ -0,0 +1,33 @@ +# -*- coding: utf-8 -*- +""" +Created on Wed May 9 09:36:51 2018 + +@author: sun_y +""" + +""" +Given two lists Aand B, and B is an anagram of A.
