8月1日 的 Guess the Number 應用程式分析

Rules of the game: The sequence of 4 numbers is set. Numbers from 0 to 9 are used. The numbers do not repeat. Your task is to guess this sequence for the minimum number of attempts. You enter 4 numbers (all cells must be filled with numbers), the program processes them and gives you a result-hint in the form of two numbers. The first number is the number of guessed digits that make up the sequence of numbers, and the second is the number of digits in which their position is guessed. The victory will be the result of 4 - 4 - it means that all 4 numbers are guessed, and they all stand in their places. For example: The sequence 9 0 5 4 is set. You entered the numbers 1 0 4 8 The program will give a hint of 2 - 1. This means that you guessed the 2 numbers that are present in the sequence of numbers (0 and 4), but only 1 is in its place (this is the 0 digit). You entered the numbers 9 0 4 7 The program will give a hint of 3 - 2. This means that you have guessed 3 numbers that are present in the sequence of numbers (9, 0 and 4), but only 2 of them stand in their place (these are the numbers 9 and 0).
