Print word pattern - odd letters - beginner's code

1. Print the word with odd letters as P M R A O R G O R R A P M Solution: using System; public class Test { public static void Main() { string text = Console.ReadLine(); int n=text.Length; Pattern print = new Pattern (); print.XPattern(text,n); } } public class Pattern { public void XPattern(string text,int n) { char[] textarray = text.ToCharArray(); int reverseprinter = n-1; int middleLetter = n/2; for(int i=0;i<n;i++) { for(int j=0;j<n;j++) { if(i==j && j!=middleLetter) { Console.Write(textarray[j]); } else if(j==reverseprinter) { Console.Write(textarray[reverseprinter]); reverseprinter--; } else { Console.Write("*"); } } Console.WriteLine(); } } } OUTPUT Please Enter text: INPUT : program p m r a o r g o r r a p m

GRANDSON PROBLEM

https://www.geeksforgeeks.org/zoho-interview-set-1-campus/ Given a two dimensional array of string like <”luke”, “shaw”> <”wayne”, “rooney”> <”rooney”, “ronaldo”> <”shaw”, “rooney”> Where the first string is “child”, second string is “Father”. And given “ronaldo” we have to find his no of grandchildren Here “ronaldo” has 2 grandchildren. So our output should be 2. SOLUTION using System; public class Test { public static void Main() { var noOfInputs = Console.ReadLine(); int noOfInputLines = Convert.ToInt32(noOfInputs); string[,] FatherSonArray= new String[noOfInputLines,noOfInputLines]; for(int father=0;father<noOfInputLines;father++) { for(int son=0;son<2;son++) { FatherSonArray[father,son] = Console.ReadLine(); } }     Console.WriteLine("No of grandchildrens:");     string GrandFather = Console.ReadLine();     int NoOfGrandSons=0;     Console.WriteLine(GrandFather);     s
