Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. Analysis. The simplest solution is using PriorityQueue. The elements of the priority queue are ordered according to their natural ordering, or by a comparator provided at the construction time (in this case). Java Solution Another similar problem is " merge k sorted lists ". This problem can be solved by using a heap. The time complexity is O (nlog (k)), where n is the total number of elements and k is the number of arrays. It takes O (log (k)) to insert an element to the heap and it takes O (log (k)) to delete the minimum element.

May 26, 2020 · Approach: The idea becomes clear once we start looking at the k arrays as the intermediate state of the merge sort algorithm. Since there are k arrays that are already sorted, merge the k arrays. Create a recursive function which will take k arrays and divide them into two parts and call the function recursively with each half. In the recursive function, if the value of k is 1 then return the array else if the value of k is 2 then merge the two arrays in linear time and return the array. If the value of k is greater than 2 then divide the group of k elements into two equal halves and recursively call the function, i.e 0 to k/2 array in one recursive function and k/2 to k array in another recursive function.
