What is TRUE about SHELL SORT
A)moves elements only one position at a time
B)moves elements long distance
C)during second phase algorithm switches to odd even transposition sort
D)both 2 and 3

Question

Quizplus · Accepted Answer

Shell sort allows for elements to be moved long distances towards their sorted position in the early stages of the algorithm, which is more efficient than moving elements only one position at a time. Additionally, during its process, it does not specifically switch to an odd-even transposition sort in its second phase; instead, it reduces the gap between elements being compared until the gap is 1, effectively becoming an insertion sort. The combination of choices B and C is incorrect because the algorithm does not switch to odd-even transposition sort, making D (both 2 and 3) incorrect based on the provided options. However, if considering the correct interpretation of Shell sort's characteristics, the answer focusing on the capability of moving elements long distances is accurate. Thus, acknowledging a misunderstanding in the explanation, the correct aspect is that Shell sort indeed moves elements long distances (B), but the mention of switching to odd-even transposition sort (C) is inaccurate, making the initial selection of D incorrect based on the provided explanation.
