Find all possible combinations of k numbers that add up to a number n, given that only numbers from 1 to 9 can be used and each combination should be a unique set of numbers. Ensure that numbers within the set are sorted in ascending order. Example 1: Input: k = 3, n = 7 Output...
Example 1:Input: candidates = [2,3,6,7], target = 7, A solution set is: [ [7], [2,2,3] ] 我们先来看一下combination sum最基本的例子,从一个无重复元素的数组中,找出所有可以使数字和为target的组合,数组中的数字可以无限制重复被选取。
代码如下 $f = 0 $tmp = Array.new $res = Array.new def combination_sum3(k, n) if (k > 9) or (k < 1) or (n > 9) or (n < 1) return $res end f = $f + 1 if (n < (2 * f + k - 1 ) * k / 2) && (k != 1 ) ...
输入: k = 3, n = 7 输出: [[1,2,4]] 示例2: 输入: k = 3, n = 9 输出: [[1,2,6], [1,3,5], [2,3,4]] 链接:https://leetcode-cn.com/problems/combination-sum-iii 著作权归领扣网络所有。商业转载请联系官方授权,非商业转载请注明出处。
