Valgrind is a toolkit for debugging and profiling, and checking for memory problems is just one of its most well-known uses. Introduce today, the Cachegrind in the Valgrind Toolkit. For a specific introduction to Cachegrind, see Valgrind's online

To find prime numbers by filtering methodHere's a common method of prime numbers.However, it is unreasonable to ask for many primes, and each number has a traversalI found this screening method very good today.Find all primes within a limitWikipedia

[Problem]Given a string S, find the longest palindromic substring in s. The maximum length of S is assume, and there exists one unique longest palindromic substring.[Analysis]There are many ways of thinking about this problem, and there are various

The operator in C is sizeof (type_name) and can be used with any variable name, type name, or constant value, and it does not need parentheses when used for variable names (not array names) or constants. Note that sizeof is an operator, and it works
