LeetCode 之 Majority Element 找出数组中出现次数大于n/2次的元素。 1.先排序,处于中间n/2处的元素必然是要求的元素,道理很简单,就算把其他元素全放在前半部分或者后半部分也都会占不满的,中间的永远是majority element; 2.暴力,把每个元素出现次数记录下来,一旦大于n/2,就结束。由于每次都要与之前遍历过的元素...
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...
Given an array of size n, find the majority element. The majority element is the element that appearsmore than⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array. 本题难度Easy。有3种算法分别是:哈希法、排序法...
