Given a collection of candidate numbers (candidates) and a target number (target), find all unique combinations in candidates where the candidate numbers sum to target.
Each number in candidates may only be used once in the combination.
Note: The solution set must not contain duplicate combinations.
\n\n\n
Example 1:
\n\n\nInput: candidates = [10,1,2,7,6,1,5], target = 8\nOutput: \n[\n[1,1,6],\n[1,2,5],\n[1,7],\n[2,6]\n]\n\n\n
Example 2:
\n\n\nInput: candidates = [2,5,2,1,2], target = 5\nOutput: \n[\n[1,2,2],\n[5]\n]\n\n\n
\n
Constraints:
\n\n1 <= candidates.length <= 1001 <= candidates[i] <= 501 <= target <= 30给定一个候选人编号的集合 candidates 和一个目标数 target ，找出 candidates 中所有可以使数字和为 target 的组合。
candidates 中的每个数字在每个组合中只能使用 一次 。
注意：解集不能包含重复的组合。

示例 1:
\n\n\n输入: candidates =\n\n[10,1,2,7,6,1,5], target =8,\n输出:\n[\n[1,1,6],\n[1,2,5],\n[1,7],\n[2,6]\n]
示例 2:
\n\n\n输入: candidates = [2,5,2,1,2], target = 5,\n输出:\n[\n[1,2,2],\n[5]\n]\n\n
