原题地址 遍历所有小孩的分数 1. 若小孩的分数递增,分给小孩的糖果依次+12. 若小孩的分数递减,分给小孩的糖果依次-13. 若小孩的分数相等,分给小孩的糖果设为1 当递减序列结束时,如果少分了糖果,就补上,如果多分了糖果,就减掉 究竟补多少或减多少,这很容易计算,不啰嗦了. 时间复杂度:O(n) 代码: int candy(vector<int> &ratings) { int n = ratings.size(); ; ; ; ; i < n; i++) { ]) { pr…

题目要求的比它的邻居比自己奖励,因此,我们有最少一个多的.所有我们可以找到所有的坑,凹坑例如,存在以下三种情况. 找到全部的凹点后,我们就能够从凹点处開始向左右两个方向依次查找递增序列.当中每一个高的都要比相邻的矮的多一个.比方1,2,5,4.我们找到凹点为1 和4,那么从1開始向左没有其它点,我们向右,依次得到2 比1高,2的糖果应该是1的基础上加1.为2, 5比2高,5的糖果是在2的基础上加1,为3. 令一个凹点4, 向左,5比4高,5的糖果应该是在4的基础上加 1,为2,这时我们发现冲突了…

要求的条件是: 1.每个人最少一个糖果. 2.相邻的小朋友,要保证,评分高的比评分低的糖果多. 如果从一侧扫描的话,容易确定的就是递增序列,只要上升1个就够了. 容易出现问题的就是:遇到下降期,或者相邻的数相等,要怎么处理. 直接给1?或者减1?不行,搞不好可能出现负数. 比如 1 2 4 3 2 1 0 3 4 5 6 这种情况下,1~4每次只增加1,到后面递减的时候,右侧就会出现负数了. 但是,从最低值到最高值之前递增的那些,是正确的值. 具体方法:不是我自己想出来的,唉 惭愧啊!我不会做.…

1. 题目 2. 解答 初始化左序奖赏全为 1,从左往右遍历,如果右边的人评分比左边高,右边奖赏比左边奖赏增 1. 初始化右序奖赏全为 1,从右往左遍历,如果左边的人评分比右边高,左边奖赏比右边奖赏增 1. 左序奖赏和右序奖赏的最大值就是该孩子的最终奖赏值. class Solution { public: int candy(vector<int>& ratings) { int n = ratings.size(); vector<int> left_reward(n,…
