Solution: Combination Sum
Explore how to solve the Combination Sum problem using dynamic programming. Understand how to build solutions by storing intermediate results to avoid repeated calculations, leading to efficient code that handles large input and target values with optimized time and space complexity.
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
