https://leetcode.com/problems/swim-in-rising-water/ my thought and code https://paste.ubuntu.com/p/gfpyZWFbxD/ input grid = [[3,2],[0,1]] expected 3 為什麼呢? 出發位置在 (0,0), 高度為3, 比右邊和下面兩格都要高,不能一口氣直接游過去嗎? Now rain starts to fall. At time t, the depth of the water everywhere is t t時刻,每個格子的水量都是t ? You can swim from a square to another 4-directionally adjacent square if and only if the elevation of both squares individually are at most t 這兩句關鍵的敘述看不太懂 ~~ 之前做過the maze ii (題目付費會員才能看) https://leetcode.com/problems/the-maze-ii/ 題目可以看這篇blog https://www.cnblogs.com/grandyang/p/6725380.html 我本以為 778這題和the maze ii BFS解法一樣 只要隔壁滿足某些條件,就可以一直往隔壁走 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 73.189.14.17 (美國) ※ 文章網址: https://www.ptt.cc/bbs/Prob_Solve/M.1560235164.A.722.html
