一个国外的java数列题目 Divide & Conquer 1. Sub-problems need not leave the main problem type unchanged 2. Sub-problems need not be of the same type 3. Integration of the sub-problems need not be easily accomplished, i.e., they may not be solved by “direct observation”. Recursion 1. Removal of a sub-problem from the original problem leave s the problem type unchanged until a residual problem is so simple that it can be solved in a “direct manner”, i.e., the base case 2. Recursion is a special case of the Divide & Conquer category. 3. A recursive method always calls itself until the base case is reached. s the problem type unchanged until a residual problem is so simple that it can be solved in a “direct manner”, i.e., the base case 2.
