Question

in the context of divide - and - conquer algorithms, what does the conquer step typically involve?
select one
a. merging the subarrays.
b. solving the subproblems directly.
c combining the solutions of the subproblems.
d. breaking the problem down into smaller pieces.

Explanation:

Divide - and - conquer algorithms have three main steps: dividing the problem (like breaking it into smaller pieces, which is similar to option D), solving the sub - problems (not directly as in option B, but recursively), and combining the solutions (option C). Merging sub - arrays (option A) is a specific operation in some divide - and - conquer algorithms (like merge sort), but the conquer step typically involves combining the solutions of sub - problems.

Answer:

C. Combining the solutions of the subproblems.
