今天遇到的题都挺难的,不容易有会做的. 下面是代码,等明天看看Discuss里面有没有简单的方法~ Majority Element My Submissions Question Total Accepted: 79833 Total Submissions: 208075 Difficulty: Easy Given an array of size n, find the majority element. The majority element is the element that…

题目概述: Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array. 解题思路: 这个题解法很多,官方就给了七种…

Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array. 思路: 找主要元素,用major记录主要字母,n记录ma…

题目: 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. 思路: 首先,我们来看一下怎样求众数,也就是元素出现大于⌊ n/2 ⌋的数. 我们注意到这样一个现象: 在任何数组中,出现次数大于该数组长度一半的值只能有一个. 通过数学知识,我们可以证明它的正确…

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. 思路: [LeetCode 169]Majority Element 的拓展,这回要求的是出现次数超过三分之一次的数字咯,动动我们的大脑思考下,这样的数最多会存在几个呢,当然是2个嘛.因此,接着上一题的方…

[CF886E]Maximum Element 题意:小P有一个1-n的序列,他想找到整个序列中最大值的出现位置,但是他觉得O(n)扫一遍太慢了,所以它采用了如下方法: 1.逐个遍历每个元素,如果这个元素比当前记录的最大值大,则令最大值等于当前元素,并令cnt=02.如果这个元素没有当前元素大,则cnt++.3.如果cnt=k,则返回当前最大值 现在小P想知道有多少种序列在使用他的方法时会得到错误的答案.为了简化问题,我们假定原序列是一个1-n的排列.即我们要求的是:给定n和k,有多少个1-n的…

Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array. 思路: 找到一个数组中出现次数超过一半的数.排序.哈希等…

题目:Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array. int majorityElement(vecto…

Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array. 题解:设置两个变量,一个是current,初始化为A[0…
