[Google] LeetCode 1631 Path With Minimum Effort 优先队列
You are a hiker preparing for an upcoming hike. You are given heights, a 2D array of size rows x columns, where heights[row][col] represents the height of cell (row, col). You are situated in the top-left cell, (0, 0), and you hope to travel to the bottomCodeforces 1631 F. Flipping Range —— 位置取模的DP,有丶东西
This way 题意: 给你长度为n的数组a,和一个长度的集合B,你每次可以在B中任意挑选一个长度x来给a某个对应长度的区间的数值正负反转。问你最终a中的值之和最大是多少。 题解: 这道题不错啊,dp打开了新的世界,暂时还没看到评分,不过这种我有想法但是有点不知道怎么实现的题目一般都是Codeforces 1631 D. Range and Partition —— 尺取,贪心,一点点想法
This way 题意: 给你n个数,你要将其分成k个区间,并且任意一个区间中,值在[x,y]中的数的个数要大于值不在[x,y]中的数的个数。问你y-x要最小的话,x和y分别是什么,并且要将这k个区间的左右端点输出。 题解: 嗨呀,果然是水题以前做太少基础都不扎实了,做到这种有那么一点点需要思考的题1631. Path With Minimum Effort
You are a hiker preparing for an upcoming hike. You are given heights, a 2D array of size rows x columns, where heights[row][col] represents the height of cell (row, col). You are situated in the top-left cell, (0, 0), and you hope to travel to the bott1631低洼地
描述 一组数,分别表示地平线的高度变化。高度值为整数,相邻高度用直线连接。找出并统计有多少个可能积水的低洼地? 如图:地高变化为0 1 0 2 1 2 0 0 2 0 输入 两行,第一行n,表示有n个数。第2行连续n个数表示地平线高度变化的数据,保证首尾为0。(3<=n<=10000,0<=高度<=1000) 输出[LeetCode] 1631. Path With Minimum Effort
