What is the input for merging algorithm?a.Unsorted arrayb.Two arraysc. Integersd.Characters

Analysis of the Question

To determine the input for a merging algorithm, we need to consider what a merging algorithm typically does. Merging algorithms combine multiple input collections into a single, sorted collection.

Options Present

1. Unsorted array - This may be input to a sorting algorithm but not directly for merging.
2. Two arrays - This is the primary scenario for merging, especially in the context of merging sorted arrays.
3. Integers - While integers can be elements within an array, they do not represent a structure for merging on their own.
4. Characters - Similar to integers, characters can be part of an array but are not a valid input format for a merging algorithm by themselves.

Final Answer

The correct input for a merging algorithm is b. Two arrays. This is typically how merging algorithms are structured, specifically when merging sorted arrays into a single sorted array.
