nodiscard |
Constructs a Perm initialized using the container cont as follows: the image of the point i under the permutation is the value in position i of the container cont.
- Template Parameters
-
| Return | the return type. Must satisfy IsPerm<Return>. |
| OtherContainer | universal reference for the type of the container. |
- Parameters
-
- Returns
- A Perm instance with degree
N.
- Exceptions
-
| LibsemigroupsException | if any of the following hold:
- the size of
cont is incompatible with container_type.
- any value in
cont exceeds cont.size() and is not equal to UNDEFINED.
- there are repeated values in
cont.
|
- Complexity
- Linear in the size of the container
cont.
◆ make() [2/2]
template<typename Return>
Constructs a Perm initialized using the container cont as follows: the image of the point i under the permutation is the value in position i of the container cont.
