Swift Algorithms 0.2.0

Additions

Two new additions to the list of algorithms:

• adjacentPairs() lazily iterates over tuples of adjacent elements of a sequence. (#119)
• minAndMax() finds both the smallest and largest elements of a sequence in a single pass. (#90)

Changes

• When calling chunked(on:), the resulting collection has an element type of (Subject, SubSequence) instead of just SubSequence, making the subject value available when iterating.

  let numbers = [5, 6, -3, -9, -11, 2, 7, 6]
  for (signum, values) in numbers.chunked(on: { $0.signum() }) {
      print(signum, values)
  }
  // 1 [5, 6]
  // -1 [-3, -9, -11]
  // 1 [2, 7, 6]

Fixes

• Improvements to the documentation and PR templates.
