Article Introduction：01 Fixed window Fixed window, also known as fixed window (also known as counter algorithm, FixedWindow) current limiting algorithm, is the simplest current limiting algorithm. It controls the maximum number of visits within the unit of time through a counter maintained within the unit of time. Assume that the number of requests per minute is limited to no more than 60, and a counter is set. When a request arrives, if the counter reaches the threshold, the request is rejected, otherwise the counter is incremented by 1; the counter is reset to 0 every minute. The code is implemented as follows: publicclassCounterRateLimiterextendsMyRateLimiter{/***Limit the number of requests per second*/privatefinallongpermitsPerSecond;

Article Introduction：I'm making a simple hangman game with go but I'm running into a bug where the unknown_string string (which will be shown in the code) has _ characters so other players guessing the letters can see the length of the word and whenever the player types correctly of a letter, I want it to replace the nth (n depends on the index where the letter is found in the word) _ character with that letter, this has been successful, but there is a problem. If a word has two repeated letters, only one of them is replaced. I created a separate function called iterate (this function is because I want to avoid nested code) to iterate over all indexes. But it doesn't work, the code is as follows: packagemainimport(
