The replacement must be in-place, do not allocate extra memory. Given a set of candidate numbers (candidates) (without duplicates) and a target number (target), find all unique combinations in candidates where the candidate numbers sums to target. Solution: this is not exactly backtracking problem, however, we recursively add the next digit to the previous combinations. It will still pass the Leetcode test cases as they do not check for ordering, but it is not a lexicographical order. Maximum Length of Pair Chain. Next Permutation (Medium) Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. Nick White 13,543 views 1 Answer +1 vote . Range Sum Query - Immutable . 0 votes . Elements in a combination (a 1, a 2, … , a k) must be in non-descending order. Given two integers n and k, return all possible combinations of k numbers out of 1 ... n. For example, If n = 4 and k = 2, a solution is: [ [2,4], [3,4], [2,3], [1,2], [1,3], [1,4], ] 解题方法.
