We reverse a string by converting it into an array of characters and reversing the character array with the Array.Reverse() function. The following code example shows us how we can reverse a string with the Array.Reverse() function in C#. using System; namespace reverse_string { class ...
Each of these functions returns a pointer to the alteredstring. Noreturnvalueisreserved to indicate an error.

Another good alternative is to construct an inverse map std::unordered_map<V,K> from the original map std::unordered_map<K,V> that can easily do the reverse lookup in constant time. We can easily build the inverse map by iterating the original map using a simple for-loop or range-base...
151. Reverse Words in a String (快慢指针) Given an input string, reverse the string word by word. Example: the skyisblue blueissky the Note: A word is defined as a sequence of non-space characters. Input string may contain leading or trailing spaces. However, your reversed string ...
C++ String: Exercise-32 with Solution Write a C++ program that takes a string and reverses the words of three or more lengths in a string. Return the updated string. As input characters, only spaces and letters are permitted. Sample Data: ...
The C++ has in its Standard Library std::string, which provides much simpler user interface to "strings" than the C's functions that operate on "C-strings". There is an another question though (just to be sure): Does the strrev() modify the array into which the s points to? If yes...
This post will discuss how to reverse all key-value pairs of a map in C++. The values in the map may or may not be unique... The idea is to loop over the map and insert each key-value pair into the new map in reverse order.
