比赛总结 题目题意:有f种口味的糖果,现在要把每颗糖果分到一些packs里面去。packs分两种:flavored pack:只有一种口味。variety pack:每种口味都有。求满足下列要求的分法有多少种:1、每个pack至少有两颗糖果。2、所有pack的糖果数相同。3、variety pack 里每种口味的糖果数量相同。4、至少一个variety pack。5、每种口味至少一个flavored pack。 题解:设一个pack 的糖果数为lim。由3知lim是f的倍数。并且去掉variety packs后,剩下的每种糖果间的差值还跟原来一样,要将它们分完必须都是lim的倍数,也就是差值也

题目大意一直线上站了N个孩子,每个孩子都有一个属于自己的数字,现在按照如下规则给孩子分发糖果:每个孩子至少有一个糖果;相邻的孩子中数字比较大的那个拿的糖果也比较多。求最少要发掉多少个糖果。解题思路贪心法。 想象下,先从前面开始升序遍历,所有升序的就从1开始给,再从后面开始升序遍历,所有升序的就从1开始给,遇到所有需要改变值的节点,对比想要改成的值与之前的值,取最大的保证其对两边都是最大。代码cla

贪心法 复杂度 时间 O(N) 空间 O(N) 思路 典型的贪心法,如果一个孩子比另一个孩子的分高,我们只多给1块糖。我们可以先从左往右遍历,确保每个孩子根他左边的孩子相比,如果分高,则糖要多1个,如果分比左边低,就只给一颗。然后我们再从右往左遍历,确保每个孩子跟他右边的孩子相比,如果分高则糖至少多
