"""给你两个整数数组 nums 和 index。你需要按照以下规则创建目标数组:
目标数组 target 最初为空。
按从左到右的顺序依次读取 nums[i] 和 index[i],在 target 数组中的下标 index[i] 处插入值 nums[i] 。
重复上一步,直到在 nums 和 index 中都没有要读取的元素。
请你返回目标数组。
题目保证数字插入位置总是存在。
示例 1:
输入:nums = [0,1,2,3,4], index = [0,1,2,2,1]
输出:[0,4,1,3,2]
解释:
nums index target
0 0 [0]
1 1 [0,1]
2 2 [0,1,2]
3 2 [0,1,3,2]
4 1 [0,4,1,3,2]
示例 2:
输入:nums = [1,2,3,4,0], index = [0,1,2,3,0]
输出:[0,1,2,3,4]
解释:
nums index target
1 0 [1]
2 1 [1,2]
3 2 [1,2,3]
4 3 [1,2,3,4]
0 0 [0,1,2,3,4]
示例 3:
输入:nums = [1], index = [0]
输出:[1]
提示:
1 <= nums.length, index.length <= 100
nums.length == index.length
0 <= nums[i] <= 100
0 <= index[i] <= i
