在字符串递归中将数字左移

function leftShiftNumbersInString(inputString) {
  // Step 1: 提取数字
  let numbers = inputString.match(/\d+/g);

  // Step 2: 左移数字
  let shiftedNumbers = numbers.map(number => {
    return parseInt(number) << 1; // 左移一位，相当于乘以2
  });

  // Step 3: 插入左移后的数字到原字符串中
  for (let i = 0; i < numbers.length; i++) {
    inputString = inputString.replace(numbers[i], shiftedNumbers[i]);
  }

  // Step 4: 递归操作
  if (inputString.match(/\d+/g)) {
    return leftShiftNumbersInString(inputString);
  } else {
    return inputString;
  }
}

// 示例调用
let input = "abc12def34ghi";
let result = leftShiftNumbersInString(input);
console.log(result);
