Hello, I'm Monday.We have talked about merging and sorting in recent algorithms. We'll open another one today. Two more questions.1, Greater than twice the number on the rightI'm afraid everyone will forget Merge sort , so practice with a question first.1. Title DescriptionFind the number in the given array that the current number is greater th ...

Before learning the tree array to solve the reverse pair. First, let's briefly learn about tree arrays. First, let's explore four problems. 1. What is a tree array? See the name and meaning, is to use arrays to simulate tree structures. Then another question arises, why not make achievements directly? The answer to this question is not ne ...

Part II C + + standard library The core of the standard library is many container classes and a family of generic algorithms. These facilities can help us write concise and efficient programs. The standard library will pay attention to the details of bookkeeping operations, especially memory management, so that our programs can devote all thei ...

1. Algorithm complexity: The time complexity and space complexity of the algorithm are collectively referred to as the complexity of the algorithm. Time complexity: time complexity refers to the calculation workload required to execute the algorithm; Space complexity: it is a measure of the amount of storage space temporarily occupied by ...
