The single list is the sorted list The merge algorithm is used repeatedly in the merge sort algorithm An example merge sort is given in the illustration It starts with an unsorted array of 7 integers. Most implementations of merge sort are stable, which means that the relative order of equal elements is the same between the input and output These merge algorithms generally refer to merge algorithms that take in a number of sorted lists greater than two
Merge algorithms there are many different approaches to automatic merging, with subtle differences [6] group the elements of into pairs of elements, arbitrarily, leaving one element unpaired if there is an odd number of elements Perform comparisons, one per pair, to determine the larger of the two elements in each pair. It is a greedy algorithm, and a generalization of huffman's original algorithm. It gets its name from the observation that merging two sorted lists, a and b, is equivalent to breaking a into evenly sized blocks, inserting each a block into b under special rules, and merging ab.
