Problem Statement

Problem Statement

Cat Snuke came up with some problems. He wants to construct as many problem sets as possible using those problems. Each problem set must contain exactly three problems: one for the Easy slot, one for the Medium slot, and one for the Hard slot. Each problem can only be assigned to a single slot in a single problem set. He came up with E + EM + M + MH + H problems in total. The distribution of the problems is as follows:
  • E problems can only be used in the Easy slot.
  • EM problems can be used either in the Easy slot or the Medium slot.
  • M problems can only be used in the Medium slot.
  • MH problems can be used either in the Medium slot or the Hard slot.
  • H problems can only be used in the Hard slot.
Return the maximal number of problem sets he can construct.

Constraints

  • E, EM, M, MH, H must be between 0 and 100000, inclusive.
