srotate-right input-seq rotate the input sequence right one step srotate-right[n] input-seq rotate the input sequence right n steps, modulus size(input-seq)
srotate-right (|one> . |two> . |three> . |four> . |five>) |five> . |one> . |two> . |three> . |four> srotate-right[3] (|one> . |two> . |three> . |four> . |five>) |three> . |four> . |five> . |one> . |two> -- 11 mod 5 == 1, so rotate right 1 step: srotate-right[11] (|one> . |two> . |three> . |four> . |five>) |five> . |one> . |two> . |three> . |four>
