Arrays.sort(T[], Comparator < ? super T > c) is a method for sorting user-defined object array. The official Java Doc briefly describe what it does, but not much for deep understanding. In this post, I will walk though the key information for deeper understanding of this method. 1. ...
for each of the primitive data types, but Java doesn’t provide this for you. Some sort of templatizing mechanism might someday provide a better way for Java to handle this problem. [32] Returning an array Suppose you’re writing a method and you don’t just want to return one thing...
Since the partition procedure has linear time complexity, the overall time complexity, in this case, is quadratic. This is the worst-case scenario for our input array. 3. Three-way Partitioning To efficiently sort an array having a high number of repeated keys, we can choose to handle the ...
Time complexity: O(nlogn) publicclassSolution {publicint[] intersect(int[] nums1,int[] nums2) { List<Integer> res =newArrayList<Integer>(); Arrays.sort(nums1); Arrays.sort(nums2);for(inti = 0, j = 0; i< nums1.length && j<nums2.length;){if(nums1[i]<nums2[j]){ ...
