38. Never redefine inherited default parameter values.Redefining a function's default parameter value means redefining the function, not the virtual function, so you will consider the reason why you cannot redefine the default parameter values for virtual functions: Virtual functions are dynamically bound and default parameter values are statically bound.A static type is a type declared in a program, whereas a dynamic type refers to the type of the ac

Sequential traversalSequentially scans the array once, counting the number of occurrences of that figure.Time complexity: O (N)2, two-point searchAssuming that the number we are looking for is k, then we need to find the first k in the array and the position where the last K appears.How can I find the position of the first k by two points?The numbers in the middle of the array are compared with K,If the number is large

auto-incrementing sequence value of the table's primary key, and inserts data rows from a specific state file into the table to reset the table. Sometimes, we may not want to reset each table described in a specific state file before a set of tests, because resetting too many specific state files may take a lot of time. in this case, we can write a PHP script to customize the initialization process. this script should be saved in the directory where the specified state file is stored and namedi
