This article will explain in detail how LeetCode solves the problem of portfolio summation. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Title

Given an array candidates without repeating elements and a target number target, find all the combinations in candidates that can make the sum of numbers target.

Numbers in candidates can be selected indefinitely.

Description: all numbers (including target) are positive integers. The solution set cannot contain duplicate combinations. Example 1: input: candidates = [2dje 3je 6je 7], target = 7, the solution set is: [[7], [2je 2je 3]] example 2: input: candidates = [2je 3je 5], target = 8, the solution set is: [2m 2m 2m 2J 2], [2m 3e 3], [3J 5] hint: 1
