from typing import List
# 这道题很容易能够想到，只需要遍历两边列表就可以了
# 两层循环
class Solution:
def twoSum(self, numbers: List[int], target: int) -> List[int]:
# 第一次遍历列表
for index1 in range(len(numbers)):
# 注意这里，如果有重复的值可以直接跳过
if index1 != 0 and numbers[index1] == numbers[index1 - 1]:
continue
# 遍历index1后边的值，与numbers[index1]相加，判断是否等于目标值
for index2 in range(index1 + 1,len(numbers)):
if numbers[index1] + numbers[index2] == target:
return [index1 + 1,index2 + 1]
