Insert

Adds a key to the set.

Module: Std::HashSet

Signature

func Insert(self, key: int);

Parameters

Name	Type	Description
key	int	The key to add.

Description

Adds key to the set. If the key is already present, the call has no effect, so the set never holds duplicates. It grows automatically as it fills.

Example

import Std::HashSet::*;

var set: HashSet;
Init(&set);
set.Insert(7);
set.Insert(7);               // no-op; still one element
set.Free();
