Index out of range error

Question

Hi all This is the code below which gives me the error mentioned in subject: Here i want to extract the unique elements: output should be {1359} public static void Main() { int[] number={113335559999}; int n = number.Length; for (int i = 0; i { if (number[i] != number[i + 1]) { Console.WriteLine(number[i]); } } } Thanks in advance

Vulpes · Answer

Yes Santhosh is right: public static void Main() { int[] number={993 115553399}; int n = number.Length; Array.Sort(number); Console.WriteLine(number[0]); for (int i = 1; i { if (number[i] != number[i - 1]) { Console.WriteLine(number[i]); } } }

I checked Vulpes code.Its working fine

Why is this code given by Vulpes not printing 1? public static void Main() { int[] number={993 115553399}; int n = number.Length; Array.Sort(number); Console.WriteLine(number[0]); for (int i = 1; i { if (number[i] != number[i - 1]) { Console.WriteLine(number[i]); } } }

hi Rani Santosh and Vulpes both are right you can also use linq to object for sorting and get distinct value int[] number = { 9 9 3 1 1 5 5 5 3 3 9 9 }; int[] mynumber = number. Distinct().OrderBy (num => num).ToArray(); foreach (int i in mynumber) { Console.WriteLine(i); } hope this will help you.

Vulpes · Answer

Rani Did you change the for statement so that 'i' starts from 1 rather than 0?

rani m mk · Answer

Vulpes Its still gives me the same error... In the if statement why have you changed it to i-1

rani m mk · Answer

Santosh Kumar Sir It is sorted list only

Santhosh Kumar Jayaraman · Answer

The above traditional method wont work if the items are unsorted. Sorting should be done first to get unique items if you go with traditional method

Vulpes · Answer

If you haven't yet learned LINQ and extension methods you can also do it using 'traditional' code as follows: public static void Main() { int[] number={113335559999}; int n = number.Length; Console.WriteLine(number[0]); for (int i = 1; i { if (number[i] != number[i - 1]) { Console.WriteLine(number[i]); } } }

Santhosh Kumar Jayaraman · Answer

Try this. .Distinct() extension method will helps you to get unique element. public static void Main() { int[] number = { 1 1 3 3 3 5 5 5 9 9 9 9 }; foreach (int i in number.Distinct()) { Console.WriteLine(i); } Console.Read(); }
