The system randomly selects a number between 1 and 100 as a target. The player enters a number and the system tells you whether it is "too big" or "too small." Follow the prompts and continue to narrow the range until you correctly guess the target number.
The optimal strategy is dichotomy: first guess 50, based on the prompts to determine whether it is in the upper half or the lower half, and then guess the median value. This way, you can guess any number from 1 to 100 up to 7 times. Record the number of guesses you make each time and challenge yourself to be stable within 7 times.
You can adjust the range size (1-50, 1-100, 1-1000). The larger the range, the more guesses you need. The game records the best scores and encourages players to optimize their strategies. JavaScript's Math.random() generates the target number.
In the number guessing game, the system randomly generates a target number, and the player gradually narrows the range according to the size and size prompts, and uses the least number of times to guess.
