To design a small program that determines whether a given year is a leap year, we must first clarify the definition and calculation method of a leap year. First, a leap year has 366 days, while a common year has 365 days. Next, we need to determine the calculation method for leap years, which has … Read more

The following provides two methods: the manual head-tail swap method and the pointer swap method to implement a function that reverses the input string in place (i.e., swapping the head and tail characters sequentially). Both methods have a time complexity of O(n). Pointer Swap Method: #include <stdio.h> #include <string.h> // Inversion of string edit by … Read more
