"WebGeneric Multiway Merge. Recently I had a problem (not in C++) that required merging a number of sorted lists of values. This is effectively the generalised case of merging together two sorted lists. However, instead of merging them into one single list, the requirement was instead to effectively put them into "buckets" of like values. " - Multiway merging k-way merge exemplos
