题意:从最左上角的点开始,按照格子里规定的方向走,必要时可以改变方向,cost+1。问你能够顺利走到最右下角的最小的cost是多少 题解:我们用贪心的思路,从左上角开始,用BFS 计算每个格子到达时所花费的最小cost。这个方法有点像dijskra算法,区别就是不用去找最小的点,因为在BFS的时候,每一层就是最小的值。
You will initially start at the upper left cell(0,0). A valid path in the grid is a path which starts from the upper left cell(0,0)and ends at the bottom-right cell(m - 1, n - 1)following the signs on the grid. The valid path doesn't have to be the shortest. You can mod...
