Definition : seq[] ()

A sequence is represented by a sequence of elements separated by commas, without delimiters or with either ( ) or seq[...] as delimiters, for example

(1,2,3,4)
seq[1,2,3,4]

Input :

A:=(1,2,3,4) or A:=seq[1,2,3,4]

B:=(5,6,3,4) or B:=seq[5,6,3,4]

Remarks

• The order of the elements of the sequence is significant. For example, if B:=(5,6,3,4) and C:=(3,4,5,6), then B==C returns 0.
• (see also 1.35.5)
  seq([0,2])=(0,0) and seq([0,1,1,5])=[0,0,0,0,0] but
  seq[0,2]=(0,2) and seq[0,1,1,5]=(0,1,1,5)
