[LC 368]. Largest Divisible Subset


想了两种做法。第一种:用List<Integer>[] dp 记录到目前为止的subset,通过比较dp[i] 和 dp[j]的size,就可以知道当前subset的size。

举例说明:,dp开始是[[1], [2], [3], [6]];2可以整除1,dp变为[[1], , [3], [6]];3可以整除1,dp变为[[1], , , [6]];6可以整除1,2,3,但2和3对应的dp[]的size要比1对应的dp的size要大,所以把2(或3)对应的dp加到6对应的dp中,dp变成[[1], , , ]。最后结果是dp[i] 中size最大的元素。

第一种做法比较慢。第二种思路差不多,但用两个int[] 分别track目前subset的size和前一个元素的位置。一个是int[] count,初始值都是1,另一个int[] pre,初始值都是-1。

举例说明:, count开始是, 2可以整除1,count变成,pre变成[-1,0,-1,-1];3可以整除1,count变成, pre变成[-1,0,0,-1];6可以整除1,2,3,但count对应2或3的值大于对应1的值,所以count变成, pre变成[-1,0,0,1]。最后结果需要scan count和pre,先找出count中最大值对应的位置,然后从这个位置开始,从pre中找到之前一个应该在subset中的元素,直到找到全部subset中的元素。count的最大值也可以不在最后通过scan array找到,在之前update count和pre的过程中记录一下即可。 7 mots de plus


[LC 300]. Longest Increasing Subsequence


Example: nums =

比较好想的一种解法:int[] dp 存当前subsequence的最大可能长度,初始值所有元素都是1。对于例子来说,dp = 。算到 nums[2] = 3 时,3 < 5,略过,3 > 2,dp[2] = max(dp[0] + 1, dp[2]).这种解法需要O(n^2),因为每算一个dp[i],需要比较nums[i] 和 所有nums[0] – nums。 78 mots de plus
