Description:
Generate a new sequence by subtracting members of another sequence from a sequence.
Syntax:
A\B
A\x
Note:
The operation generates a new sequence by subtracting the members (or single values) of B from sequence A in order.
Parameter:
|
A |
A sequence whose length is n |
|
B |
A sequence whose length is m or a single value which can be regarded as [B] |
Return value:
A new sequence by subtracting the members (or single values) of B from sequence A in order.
Example:
|
|
A |
|
|
1 |
=[1,2,3,4]\[2,3] |
[1,4] |
|
2 |
=[1,2,3,3]\[1,3] |
[2,3], the duplicate members will not be subtracted repeatedly. |
|
3 |
=[1,2,3]\3 |
[1,2] |
