 ## Unit 2: Divide-and-Conquer Algorithms
 
-In the last unit, you learned the concept of divide and conquer. This unit delves further into the divide-and-conquer method. It provides some examples of divide-and-conquer algorithms, including Strassen’s surprising method for multiplying two square matrices. And then, we will study methods for solving recurrences, which are useful for describing the running times of recursive algorithms. One of them, the “master method,” is particularly powerful.
