WebA multiway merge or k-way merge is an extension of the binary merge operation, which receives k sorted sequences (queues) and merges the sequences into a single sorted sequence (queue). We have provided in the starter code a version of multiMerge that is built on top of your binary merge. The function is also replicated below for convenience.

WebMerge runs R1 and R2. This is carried out by first reading one block of each of these runs into input buffers. Blocks of runs are merged from the input buffers into the output buffer. When the output buffer gets full, it is written out onto disk. If an input buffer gets empty, it is refilled with another block from the same run. WebExternal sorting k-way merge sort with example
