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…

一道关于骑士救公主故事的题目. 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.我们英勇的骑士(K)最初被安置在左上角的房间里,他必须穿过地下城并通过对抗恶魔来拯救公主. 骑士的初始健康点数为一个正整数.如果他的健康点数在某一时刻降至 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会失去健康点数(若房间里的值为负整数,则表示骑士将损失健康点数):其他房间要么是空的(房间里的值为 0),要么包含增加骑士健康点数的魔法球(若…
