Solution: Combination Sum
Explore how to solve the Combination Sum problem using dynamic programming. Understand how memoization reduces redundant calculations and leads to an efficient solution, enabling you to find all unique combinations that sum up to a target from a set of distinct integers.
Statement
Given an array of distinct integers, nums, and an integer, target, return a list of all unique combinations of nums where the chosen numbers sum up to the target. The combinations may be returned in any order.
An integer from nums may be chosen an unlimited number of times. Two combinations are unique if the
frequency of at least one of the chosen integers is different.
Constraints:
-
nums.length -
nums[i] -
target
