Given an array of numbers nums, in which exactly two elements appear only once and all the other elements appear exactly twice. Find the two elements that appear only once.For example:Given nums = [1, 2, 1, 3, 2, 5], return [3, 5].Note:1.The order of
# 已知有一个已经排好序的数组.要求是,有一个新数据项,要求按原来的规律将它插入数组中. a=[1,2,3,4,5,6,7,8,9]num=int(input("input num:"))for i in a: if i>num: ind=a.index(i) a.insert(ind,num) break else:continueprint(a)
代码: t = [-10,-3,-100,-1000,-239,1] # 交换 -10和1的位置 t[5], t[t[5]-1] = t[t[5]-1], t[5] 报错: IndexError: list assignment index out of range 数组: >>> t [-10,-3,-100,-1000,-239,-10] 为什么? 等式右边 t[t[5]-1] 相当于 t[0] ,是对值-10的引用.首先是将t[5]的引用指向-10,此时 t[5] 的值变为-10,
题1.给定一个int数组,一个数sum,求数组中和为sum的任意2个数的组合 @Test public void test_find2() { int[] arr = { -1, 0, 2, 3, 4, 7, 8, 9, 10 }; int sum = 9; Arrays.sort(arr); List<TwoTuple<Integer, Integer>> result = new ArrayList<>(); int i = 0; int j = arr.lengt
Given an integer array of size n, find all elements that appear more than ⌊ n/3 ⌋ times. The algorithm should run in linear time and in O(1) space. class Solution { public: //O(n) Space compexity vector<int> majorityElement01(vector<int>&
Given an array of integers, every element appears three times except for one, which appears exactly once. Find that single one.Note:Your algorithm should have a linear runtime complexity. Could you implement it without using extra memory? class Solut
今天申请了博客园账号,在下班后阅览博客时发现了一个关于百度面试题探讨的博客(其实是个很基础的问题),此博客url为:http://www.blogjava.net/nokiaguy/archive/2013/01/30/394920.html 其中下面有人评论为: 有序列表查找显然二分啊,博主貌似对java的arrays和collections不是很熟. private static int getMinAbsoluteValue(final int[] source) { int index
