When constructing various types of data into strings, the powerful features of sprintf seldom disappoint you. Since sprintf and printf have almost the same usage, but the printing destination is different, the former is printed into the string, and

Time Complexity: if the scale of a problem is N, the time required for an algorithm to solve the problem is T (N). It is a function of N, T (n) is called the "time complexity" of this algorithm ". Gradual time complexity: when the input N increases
