如何检查一个字符串中的字母是否以相同的顺序出现在另一个字符串中

function checkSameOrder(str1, str2) {
  let pointer1 = 0;
  let pointer2 = 0;

  while (pointer1 < str1.length && pointer2 < str2.length) {
    if (str1[pointer1] === str2[pointer2]) {
      pointer2++;
    }
    pointer1++;
  }

  return pointer2 === str2.length;
}

// 示例用法
const result1 = checkSameOrder("hello", "hlo"); // 返回 true
const result2 = checkSameOrder("hello", "helo"); // 返回 false
console.log(result1);
console.log(result2);

exports.main_handler = async (event, context, callback) => {
  const str1 = event.queryString.str1;
  const str2 = event.queryString.str2;

  let pointer1 = 0;
  let pointer2 = 0;

  while (pointer1 < str1.length && pointer2 < str2.length) {
    if (str1[pointer1] === str2[pointer2]) {
      pointer2++;
    }
    pointer1++;
  }

  const result = pointer2 === str2.length;

  return {
    result: result
  };
};
