Combination Sum II

advancedlayer I6 · Backtracking5 tests

Given an array candidates of positive integers (which may contain duplicates) and a positive integer target, return every combination summing to target.

  • Each position in candidates may be used at most once
  • The returned list must not contain duplicate combinations — if the input has two 1s, the combination [1,7] appears only once even though either 1 could have produced it
  • Combinations may be returned in any order
