一些恶魔抓住了公主(P)并将她关在了地下城的右下角.地下城是由 M x N 个房间组成的二维网格布局.我们英勇的骑士(K)最初被安置在左上角的房间里,并且必须通过地下城对抗来拯救公主.骑士具有以正整数表示的初始健康点.如果他的健康点在任何时候降至 0 或以下,他会立即死亡.有些房间由恶魔守卫,因此骑士在进入这些房间时失去健康点(负整数):其他房间要么是空的(0),要么包含增加骑士身体健康的魔法球(正整数).为了尽快到达公主,骑士决定只会每次向右或向下移动一步.写一个函数来确定骑士的最低初始健康点…

原题地址 典型的地图寻路问题 如何计算当前位置最少需要多少体力呢?无非就是在向下走或向右走两个方案里做出选择罢了. 如果向下走,看看当前位置能提供多少体力(如果是恶魔就是负数,如果是草药就是正数),如果当前位置能够提供的体力比向下走所需要的最小体力还多,那么当前位置只需要1的体力就够了:否则,计算出额外需要多少体力. 如果向右走,同理. 设任意坐标(i, j)处最少需要health[i][j]的体力才能通关,则有如下递推公式: health[i][j] = min{ dungeon[i][j]…

题目链接 题目大意:从左上角到右下角,每一个格子都有各自的权值,如果权值为负,则当到达时,要失血:如果权值为正,则当到达时,要加血.当到达某个格子时,当前血量<=0,则死亡,到达不了右下角,所以此时要计算从左上角到右下角,初始应该最少携带多少血(即经过所有路径后所计算出的值),才不会死亡,能正常到达右下角. 法一:dfs,模板深搜,果断超时.要注意:更新点不是整条路径的和(与64题比较)的最小值,而是整条路径中所达到的最大的失血量,如果最大失血量>=0,则本身只需要携带1个血即可:否则本身携带…
