Merge K Sorted Arrays This problem can be solved by using a heap. The time is O(nlog(n)). Given m arrays, the minimum elements of all arrays can form a heap. It takes O(log(m)) to insert an element to the heap and it takes O(log(m)) to delete the minimum element. 1classRe...

Suppose we have different k sorted arrays. We have to merge these arrays and display the sorted result. So, if the input is like k = 3 and arrays are {2, 4},{3, 5, 7},{1, 10, 11, 12} , then the output will be 1 2 3 4 5 7 10 11 12 To solve this, we will follow...
FB面经Prepare: Merge K sorted Array,跟MergeKsortedlists不同在于,从PQ里poll出来以后不知道下一个需要被加入PQ的是哪一个所以需要写一个wrapperclass

the solution is to divide the data into chunks and apply merge sort on each chunk separately. The resulting sorted data is then saved to files. Once all chunks are sorted, the final step is to merge these chunks using the idea of merge k Sorted Arrays . This algorithm simplifies the proc...
