Divide and Conquer

  1. Divide problem to smaller subproblems. (More often than not, this just means dividing the problem in 2 however many times.)

  2. Solve the smaller subproblem.

  3. Define a method takes the solved subproblem to form a larger subproblem but is treated as a smaller subproblem.

  • Usually the most amount of ingenuity is spent on 3.
