Article Introduction：What is a checksum? In computing, a checksum is a small-sized piece of data created from a larger data set using an algorithm with the intention that any changes made to the larger data set will result in a different checksum. Checksums are often used to verify the integrity of transmitted or stored data, as errors or modifications in the data may cause the checksum to change. They can also be used to verify the authenticity of data, since checksums are typically generated using a key known only to the sender and receiver. Why do we use CHECKSUM? There are several reasons for using checksums - Error detection − Use checksums to detect errors that may occur during data transfer or storage. If the checksum of the received data does not match the original checksum, an error has occurred and the data needs to be retransmitted.

Article Introduction：Introduction In this tutorial, we develop a method for finding the maximum length of an odd-even substring. Odd parity in a substring means that the number of times 1 is repeated in the string is an odd number. Parity in C++ defines the bit set number and is 1 in numbers. There are two types of parity: even parity and odd parity. When the total number of "1"s in the binary representation is odd, it is called an odd parity string. In this tutorial, we use C++ programming concepts to find the maximum length odd parity substring. Implement 1String=101100Output=6 In the above example, the length of the maximum odd-parity substring is 6, and the substring can be 011100. The total number of 1's in this substring is 3, which is an odd number. Make it an odd parity substring. Implement 2Stri

Article Introduction：How does SpringBoot perform parameter verification? In daily interface development, in order to prevent illegal parameters from affecting the business, it is often necessary to verify the parameters of the interface. For example, when logging in, it is necessary to verify whether the user name and password are empty, when creating a user It is necessary to verify whether the email and mobile phone number formats are accurate. It would be too cumbersome to rely on code to verify interface parameters one by one, and the readability of the code would be extremely poor. The Validator framework is designed to help developers write less code during development and improve development efficiency; Validator is specially used to verify interface parameters, such as common required verification, email format verification, and the user name must be between 6 and 12. Wait...Validator
