boost::algorithm::equal() in C++ library

The equal() function in C++ boost library is found under the header 'boost/algorithm/cxx11/equal.hpp' tests to see if two sequences contain equal values. It returns a boolean value which determines if both the sequences are same or not. Syntax:

bool equal ( InputIterator1 first1, InputIterator1 second1,
 InputIterator2 first2, InputIterator2 second2 )
or 
bool equal ( InputIterator1 first1, InputIterator1 second1,
 InputIterator2 first2, InputIterator2 second2, 
 BinaryPredicate pred )

Parameters: The function accepts parameters as described below:

• first1: It specifies the input iterators to the initial positions in the first sequence.
• second1: It specifies the input iterators to the final positions in the first sequence.
• first2: It specifies the input iterators to the initial positions in the second sequence.
• second2: It specifies the input iterators to the final positions in the second sequence.
• p: It specifies the comparison predicate if specified.
Return Value: The function returns true if both the sequence are same, else it returns false. Note: The above function runs for C++14 and above. Program-1:
Output:

Sequence1 and Sequence2 are equal

Program-2:
