349. Intersection of Two Arrays&&350. Intersection of Two Arrays II 用两个 hash sets(Timecomplexity: O(n)) 对数组排序,用two pointers(Timecomplexity: O(nlogn)): 二叉树(Timecomplexity: O(nlogn)): 用排序法,将hashset换成list即可 :
These libraries provide convenient utility methods to initialize collections like Set. SinceGoogle Guavais one of the most commonly used, we’ve included an example from it. Guava has convenient methods for mutable and immutableSetobjects: Set<String> set = Sets.newHashSet("a", "b", "c");...
Use new time hash value - current time hash value and maintain the minimum diff. If minused result < 0, it is next day, add it with 24 * 60. Time Complexity: O(1). 共有4^4种组合. Space: O(1). size为4的HashSet. AC Java: 1 class Solution { 2 public String nextClosestTime(...

I had to implement some data structures for my computational geometry class. Deciding whether to implement the data structures myself or using the build-in classes turned out to be a hard decision, as the runtime complexity information is located at the method itself, if present at all. So ...
