Web9 mei 2024 · Divide the input collection of k sequences into two halves, left and right. Make a recursive call to recMultiMerge on the "left" half of the sequences to generate one combined, sorted sequence. Then, do the same for the "right" half of the sequences, generating a second combined, sorted sequence. Web24 jan. 2024 · 2) MERGING. When all we have is single elements we start merging the elements in the same order in which we have divided them. During Merging, we also sort the sub-arrays, because sorting 10 arrays of 2 elements is cheaper than sorting an array of 20 elements. In the end, we will have an array of elements, which is sorted.
