Intersection of Two Arrays II

intermediatelayer B3 · Hashing5 tests

Given two integer arrays nums1 and nums2, return the values they share including multiplicity.

  • A value must appear in the result as many times as it appears in both arrays — that is, the smaller of its two counts
  • So [1,2,2,1] and [2,2] give [2,2]
  • The result may be returned in any order
