To print a reverse string in C#, you can use the Array.Reverse
method or LINQ. Here's a simple example using Array.Reverse
:
string original = "Hello, World!";
char[] charArray = original.ToCharArray();
Array.Reverse(charArray);
string reversed = new string(charArray);
Console.WriteLine(reversed);
This code converts the string to a character array, reverses the array, and then creates a new string from the reversed array before printing it.
The use of the reverse string in C program is used to reverse the letters in the string. An example would be reverse me would be reversed to em esrever.
To reverse a number, first convert the number to a string, then reverse the string. Given your number consists of alphanumeric characters, the number must already be a string so simply reverse the string: #include<string> using std::string; string reverse (const string& s) { string str {}; for (auto c : s) str.insert (str.begin(), c); return str; } int main () { std::cout << "Enter a number: "; string s {}; std::cin >> s; std::cout << "The number in reverse is: " << reverse (s); }

Assume C#, not C: Traditional way: public string Reverse(string s) { if (string.IsNullOrEmpty(s)) return s; // "" or null char[] characters = s.ToCharArray(); Array.Reverse(characters); return new string(characters); } or as an extension method: public static string Reverse(this string s) { if (s == "") return ""; char[] characters = s.ToCharArray(); Array.Reverse(characters); return new string(characters); } The differences of the 2 methods above is on the caller (how to use Reverse()), and they may co-exist: For example: string test = "abc"; string result1 = Reverse(test); // traditional way string result2 = test.Reverse(); // call the extension

To play a C sharp ukulele chord, place your index finger on the first fret of the fourth string, middle finger on the second fret of the third string, and ring finger on the third fret of the second string. Strum all four strings to play the C sharp chord.
To play the C sharp major chord on the guitar, place your index finger on the 4th fret of the A string, your ring finger on the 6th fret of the D string, and your pinky finger on the 6th fret of the G string. Strum from the A string down to the high E string.

There are five common methods of string inversion in Python: using string slicing, using recursion, using the list reverse () method, using stack and using for loop. Use string slicing (most concise) s = "hello" reversed_ s = s[::-1] print(reversed_s) >>> olleh Use recursive def reverse_ it(string): if len(string)==0: return string else: return reverse_ it(string[1:]) + string[0] print "added " + string[0] string1 = "the crazy programmer" string2 = reverse_ it(string1) print "original = " + string1 print "reversed = " + string2 Use the list reverse() method in [25]: l = ['a', 'B', 'C','d '] ...: l.reverse() ...: print (l) ['d', 'c', 'b', 'a'] Using stack def Rev_ string(a_string): L = list (a_string) # simulate all stacking new_ string = "" while len(l)>0: new_ String + = l.pop() # simulate stack out return new_ string Use the for loop #for loop def func(s): r = "" max_ index = len(s) - 1 for index,value in enumerate(s): r += s[max_index-index] return r r = func(s) The above are the five common methods of string inversion in Python.
