From a literal analysis of the dividing method, you can see what steps are there: Dividing and decomposition breaks down the problem into smaller sub-problems, and the sub-problems are best the same or similar;Governance solves these smaller subproblems one by one;Merge merges the solved sub-problems and finally draws the solution to the original problem;From the above steps, we can see that the division and conquer algorithm is generally suitable for scenarios that meet the following conditions: The problem can be easily solved by shrinking to a certain extent;The problem can be broken down into several identical problems of smaller scale;The solutions to several sub-problems that are decomposed from the problem can be combined into the solution to the problem;Each sub-problem is independent and has no intersection with each other.
