https://oj.leetcode.com/problems/majority-element/ 题目内容: Given an array of sizen, 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. ...
过程: Runtime: O(n) — Moore voting algorithm: We maintain a current candidate and a counter initialized to 0. As we iterate the array, we look at the current element x: If the counter is 0, we set the current candidate to x and the counter to 1. If the counter is not 0, we ...
impl Solution { pub fn majority_element(nums: Vec<i32>) -> i32 { // 维护 majority ,表示众数 let mut majority = 0; // 维护 count ,表示当前众数的个数 let mut count = 0; // 遍历每个数 for num in nums { // 如果当前众数的个数为 0 ,则更新当前众数为 num if count == 0 { majo...
