js 范围内不重复随机数

function getUniqueRandomNumbers(count, min, max) {
  if (max - min + 1 < count) {
    throw new Error('范围内的数字不够生成指定数量的不重复随机数');
  }
  let numbers = [];
  while (numbers.length < count) {
    let num = Math.floor(Math.random() * (max - min + 1)) + min;
    if (!numbers.includes(num)) {
      numbers.push(num);
    }
  }
  return numbers;
}

// 示例用法
let uniqueRandomNumbers = getUniqueRandomNumbers(5, 1, 10);
console.log(uniqueRandomNumbers);

function getUniqueRandomNumbers(count, min, max) {
  let numbers = [];
  for (let i = min; i <= max; i++) {
    numbers.push(i);
  }
  for (let i = numbers.length - 1; i > 0; i--) {
    let j = Math.floor(Math.random() * (i + 1));
    [numbers[i], numbers[j]] = [numbers[j], numbers[i]];
  }
  return numbers.slice(0, count);
}

// 示例用法
let uniqueRandomNumbers = getUniqueRandomNumbers(5, 1, 10);
console.log(uniqueRandomNumbers);
