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]…
