 You can argue that `true` is the correct answer in the first case, even though the sequences are not the same. The first N entries in `seq2` are the same as the entries in `seq1` - but that's not all that's in `seq2`. But in the second case, the algorithm will read past the end of `seq1`, resulting in undefined behavior (large earthquake, incorrect results, pregnant cat, etc).

+
+The header file 'is_palindrome.hpp' contains six variants of a single algorithm, is_palindrome. 
+The algorithm tests the sequence and returns true if the sequence is a palindrome; i.e, it is identical when traversed either backwards or frontwards.
+
+The routine `is_palindrome` takes a sequence and, optionally, a predicate. It will return true if the predicate returns true for tested elements by algorithm in the sequence. 
+
+The routine come in 6 forms; the first one takes two iterators to define the range. The second form takes two iterators to define the range and a predicate. 
+The third form takes a single range parameter, and uses Boost.Range to traverse it. The fourth form takes a single range parameter ( uses Boost.Range to traverse it) and a predicate.
+The fifth form takes a single C-string and a predicate. The sixth form takes a single C-string.
+
+
+[heading interface]
+
+The function `is_palindrome` returns true if the predicate returns true any tested by algorithm items in the sequence.  
+There are six versions: 
+1) takes two iterators.
+2) takes two iterators and a predicate.
+3) takes a range.
+4) takes a range and a predicate.
+5) takes a C-string and a predicate.
+6) takes a C-string.

+
+[heading Iterator Requirements]
+
+`is_palindrome` work on Bidirectional and RandomAccess iterators.
+
+[heading Complexity]
+
+All of the variants of `is_palindrome` run in ['O(N)] (linear) time; that is, they compare against each element in the list once. If any of the comparisons not succeed, the algorithm will terminate immediately, without examining the remaining members of the sequence.
+
+[heading Exception Safety]
+
+All of the variants of `is_palindrome` take their parameters by value, const pointer or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
+
+[heading Notes]
+
+* `is_palindrome` returns true for empty ranges, const char* null pointers and for single element ranges. 
+
+* If you use version of 'is_palindrome' without custom predicate, 'is_palindrome' uses default 'operator==()' for elements.
+
+* Be careful with using not null pointer 'const char*' without '\0' - if you use it with 'is_palindrome', it's a undefined behaviour.
