In some problems involving “cycles” (such as looping playback or polling tasks), it is necessary to iterate over a given list multiple times. Here, iteration means going from the first element to the last, and then starting again from the first element, repeating this process. Let’s start with some music~ The following example will cyclically … Read more

Have you ever encountered a situation where you need to generate all permutations, such as generating all arrangements of cards in game design? Students with a certain foundation in algorithms should be very adept at using the “recursion + backtracking” approach to solve such problems. However, Python has already implemented this for us, with the … Read more

What is the essence of the C language? More than 90% of C engineers would definitely say it is pointers. Pointers are something that C engineers both love and hate. They are often a nightmare for many junior engineers, with terms like dangling pointers, wild pointers, and memory leaks… each one can make you lose … Read more
