WebApr 11, 2024 · The dense union type has a relatively succinct memory representation but doesn’t support vectorizable operations, making it less efficient during the processing phase. Conversely, a sparse union supports vectorization operations, but comes with a memory overhead directly proportional to the number of variants in the union. WebA certain string-processing language offers a primitive operation which splits a string into two pieces. Since this operation involves copying the original string, it takes n units of time for a string of length n, regardless of the location of the cut. Suppose, now, that you want to break a string into many pieces.
