string reverse without using reverse method

Question

1.I want the output like following. If the word is "STUDENT".The output will be "STTNUED" . 2.print like following * ** *** **** ***** **** *** ** *

Vulpes · Answer

On your first question, do you actually want to reverse the string or to rearrange it in some fashion? "STUDENT" reversed would be "TNEDUTS" but you say the output should be "STTNUED".

static void Main() { StringBuilder ob = new StringBuilder(" STUDENT "); StringBuilder ot = new StringBuilder(); for (int i = ob.Length - 1; i > -1;i-- ) { ot.Append(ob[i]); } Console.WriteLine(ot); Console.ReadLine(); }

Vulpes · Answer

Hopefully, the OP does just mean to reverse the string because there seems to be no discernible pattern for rearranging the string otherwise. It's more or less random.

Oh really, Vulpes I missed that. Actually I saw the subject of the question. And these are the common interview questions.

1. Actually string type is an array of character so you can use : string str="STUDENT" it has 7 characters so I can reverse it using : for(int i=7;i>=0;i--) { Console.Write(str[i]); } 2. class Program { static void Main() { for (int i=1;i { if(i for(int j=0;j { Console.Write("*"); } } else { for(int j=i+1;j { Console.Write("*"); } } Console.WriteLine(); } } }
