different of boosthash_combine boosthash_range in C++

The boost::hash_combine() and boost::hash_range() functions in C++ are both used to combine multiple hash values into a single hash value. However, they have some differences in their usage and functionality.

1. boost::hash_combine():

• This function is used to combine two hash values into a single hash value.
• It takes two hash values as input and combines them using bitwise operations.
• The resulting hash value is affected by the order of the input values.
• Example usage: boost::hash_combine(hash_value, another_hash_value);

2. boost::hash_range():

• This function is used to combine a range of hash values into a single hash value.
• It takes a range of hash values as input and combines them using bitwise operations.
• The resulting hash value is not affected by the order of the input values.
• Example usage: boost::hash_range(hash_values_begin, hash_values_end);

In summary, boost::hash_combine() is used to combine two hash values, while boost::hash_range() is used to combine a range of hash values. The main difference lies in how they handle the input values and the resulting hash value
