String reversal is not a common operation in programming, so many coding languages do not have a built-in function for reversal strings. Reversing a string is one of the most frequently asked questions in a programming technical interview, and it does have a few real-world applications. ...

The string.contains() method is used to check whether a specific string or substring is present in a series/list or any other collection or string itself. If we apply this method on a column of a DataFrame then it returns n Boolean values where n is the number of elements of that ...
In this code, thestd::reversefunction is used to reverse the characters in the string, making'n'the first character. Then, an iterator'it'is initialized to point to the first character (which was the last character before the reversal). ...
