Merge Path Search
Merge Path Search Merge path search finds partition points in two sorted arrays so that a merge can be split into independent chunks. It is mainly used for parallel merge, GPU merge, and distributed sorted data processing. The method views merging as a path through a grid. Each step consumes one element from either the first array or the second array. A diagonal in this grid represents a fixed number...
Array Merge
Array Merge Array merge combines two sorted arrays into one sorted sequence. It is a fundamental operation in merge sort and external sorting. You use it when two ordered sequences must be combined while preserving order. Problem Given two sorted arrays $A$ and $B$ of lengths $n$ and $m$, produce a sorted array $C$ containing all elements: $$ C = \text{merge}(A, B) $$ Algorithm Use two pointers and repeatedly select...
