Combination Sum

intermediatelayer I6 · Backtracking5 tests

Given an array candidates of distinct positive integers and a positive integer target, return every combination of candidates that sums to target.

  • The same candidate may be reused as many times as you like
  • Two combinations are the same if they use the same numbers the same number of times — order does not distinguish them, so return each multiset once
  • The combinations may be returned in any order
  • If nothing sums to the target, return an empty array
