LeetCode 1920. 基于排列构建数组

示例 1：

输入：nums = [0,2,1,5,3,4]
输出：[0,1,2,4,5,3]
解释：数组 ans 构建如下：
ans = [nums[nums[0]], nums[nums[1]], nums[nums[2]], nums[nums[3]], nums[nums[4]], nums[nums[5]]]
    = [nums[0], nums[2], nums[1], nums[5], nums[3], nums[4]]
    = [0,1,2,4,5,3]
示例 2：

输入：nums = [5,0,1,2,3,4]
输出：[4,5,0,1,2,3]
解释：数组 ans 构建如下：
ans = [nums[nums[0]], nums[nums[1]], nums[nums[2]], nums[nums[3]], nums[nums[4]], nums[nums[5]]]
    = [nums[5], nums[0], nums[1], nums[2], nums[3], nums[4]]
    = [4,5,0,1,2,3]

class Solution:
    def buildArray(self, nums: List[int]) -> List[int]:
        res = []
        for i in nums:
            res.append(nums[i])
        return res

if __name__ == '__main__':
    nums = [0,2,1,5,3,4]
    result = Solution().buildArray(nums)
    print(result)
