Before that, I thought that if a variable is defined as a global variable, it can change its value even if it is passed into a function in the form of a parameter.It turns out that the idea is wrong.Below I use the code to explain, the specific

For the complexity of the algorithm, an intuitive perception method is the algorithm running time for measuring a certain amount of data.As an example of the qsort provided in C, the calculation time is measured with 1 million data, and the time
