Description

One-sided Braun sequences. All running times are as listed in Data.Edison.Seq except the following:

  • lview, lcons, ltail* O( log n )
  • rcons, rview, rhead*, rtail*, size O( log^2 n )
  • copy, inBounds, lookup*, update, adjust O( log i )
  • append O( n1 log n2 )
  • concat O( n + m log m )
  • drop, splitAt O( i log n )
  • subseq O( i log n + len )
  • reverseOnto O( n1 log n2 )
  • concatMap, (>>=) O( n * t + m log m ), where n is the length of the input sequence m is the length of the output sequence and t is the running time of f

By keeping track of the size, we could get rcons, rview, rhead*, and rtail* down to O(log n) as well; furthermore, size would be O( 1 ).
