如何输入有频率的数组？

function inputFrequencyArray(arr) {
  let result = [];
  
  for (let i = 0; i < arr.length; i += 2) {
    const element = arr[i];
    const frequency = arr[i + 1];
    
    for (let j = 0; j < frequency; j++) {
      result.push(element);
    }
  }
  
  return result;
}

// 示例输入有频率的数组
const frequencyArray = [1, 3, 2, 4, 5, 2];

// 调用函数并输出结果
console.log(inputFrequencyArray(frequencyArray));
