Summary: Title.Focus:1. The following points are noted:· Large constantWe need to be sensitive to the possible large constants.· Non-deterministic inner loopThe assumption that the inner loop is the determinant is not always correct.· Instruction timeIt is not always correct to assume that the time required for each instruction execution is always the same.· System factorsA garbage collector or a JIT compiler, or a download being made from the Internet, can greatly affect the results of the expe

binary trees;Another important extension is the composite data structure: We can use the Backpack storage stack, the queue to store arrays and so on, for example, we can use an array of backpacks to represent it.It's easy to define arbitrarily complex data structures in this way, and one of the important reasons we focus on abstract data types is trying to control this complexity.3. When researching a new application area, we will follow the steps below to identify the target and use the data a

non-static (instance) methods in use case code: the beginning of a static method call is the class name (which is used in uppercase), and not the beginning of a static method call is always the object name (in the custom lowercase).7. Java passes a copy of the parameter value from the caller to the method, which is known as Pass-by-value. One important consequence of this approach is that the method cannot change the value of the Call-side variable. This strategy is exactly what we expected for

sometimes the input model) determines the order of magnitude of growth.Separating the algorithm from the specific implementation on a computer is a powerful concept because it is our knowledge of algorithmic performance that can be applied to any computer.8. We used a cost model to evaluate the nature of the Algorithm.This model defines the basic operations in the algorithm we are studying.For example, the cost model for 3-sum problems is the number of times we access array Elements.The role of

Q: What is Object-oriented? What is the difference from a process-oriented one?A: Object-oriented: The problem-oriented space, based on the abstraction of the problem;Process oriented: The solution space, based on the computer structure to abstract;Five basic features of OOP:1) All things are objects.ExplainYou can extract any conceptualization artifacts that you want to solve for a problem and represent them as objects in your program.2) programs are collections of objects that they communicate

Assigning values to variablesThe commonly used variable assignment is to use "=" to assign values.1 int 2;However, if you assign a floating-point number to I, it will result in a loss of precision, preferably in C + + using the initialization list of the way "{}" to assign a value to the variable, so as to ensure that some types of information loss may cause the conversion of the type1 #include 2usingnamespace std; 3 4 int Main () {5 int I {2.3}; 6 return 0 ; 7 }For example, the compile

With sinking operations, the heap is constructed from n elements with fewer than 2N comparisons and less than n interchanges.2. Heap sequencing plays an important role in the study of sequencing complexity, because it is the only way we know to be able

programming languages is the Lisp language invented by McCathy in the the 1950s, and the linked list is the main structure of the program and data in this language.9.

sufficient to save all the elements, without wasting too much space:If there is no extra space, we will double the length of the array;If the stack size is less than One-fourth of the array, we will halve the length of the array.In this implementation, the stack never overflows, and the usage is never less than One-fourth (unless the stack is empty, in which case the array size is 1).The textbook has the source code, fully understand!5. Even if the use case no longer requires this element, the

Summary: This section describes the realization and effect of magnification test.Focus:1. The realization of magnification test:· Develop an input generator to produce various possible inputs in real-world situations.· Run the program, which calculates the ratio of each experiment to the last run time.· Repeated operations know that the ratio is approaching the limit 2^b.This experiment is ineffective for algorithms with no limit to the ratio, but it still applies to many programs, and we can dr

Summary: As the name implies.Focus:1. Geometric objects: A Natural example of object-oriented programming is designing data types for geometric objects.Point2d.java is a data type for points in the plane.Interval1d.java is a data type for one-dimensional intervals.Interval2d.java is a data type for two-dimensional intervals.Interested to study!2. The Java language provides special support for string initialization and connection: We can create and initialize a string directly using a string lite

does not initiate assertions, and you can use the-enableassertions flag (abbreviated as-EA) at the command line to start the assertion. The purpose of the assertion is to debug: The program should not rely on assertions in normal operations, as they may be disabled. The system programming course learns to use assertions to ensure that the code is never terminated by a system error or into a dead loop. （？ ）10. If you always complain about the nature of programming language, then you can only des

exception.4. Familiarize yourself with the typical array processing code (P11-P12):· Find the largest element in an array· Computes the average of an array element· Copying an array· Reverse the order of array elements· Matrix multiplication (Phalanx)-a[][] * b[][] = c[][]5. The array name represents the entire array-if we assign an array variable to another variable, then two variables will point to the same array. If you want to copy an array, you should declare, create, and initialize a new
