Here’s how to use swap() function.
Description:
Generate a new sequence by swapping the positions of two intervals in a sequence specified by two integer sequences.
Syntax:
A.swap(p,q)
Note:
This function swaps positions between two intervals in sequence A that are respectively specified by two integer sequences that do not overlap each other.
Parameter:
|
A |
A sequence |
|
p |
An integer sequence composed of positive integers, for example [1,2,3 ], i.e. to (1,3) |
|
q |
An integer sequence composed of positive integers that doesn’t have intersection with p, for example [4,5,6], i.e. to(4,6) |
Return value:
Sequence
Example:
|
|
A |
|
|
1 |
[a,b,c,d,e,f,g.h.i.j.k] |
|
|
2 |
=A1.swap(to(1,3),to(4,6)) |
[d,e,f,a,b,c,g.h.i.j.k]. |
|
3 |
=A1.swap(to(1,4),to(4,6)) |
Error message appears because the two intervals in A3 overlap each other. |
Note:
The two intervals to be swapped in a sequence should not overlap each other.
