obtain three times repeated values in arraylist.. how..

Question

Hello my friends... I have an arraylist les say string[] list = new list{4566786738797 }; I want to identify the three times repeated values in arraylist list. e.g. program will output that: The value 6 is repeated three times.. The value 7 is repeated 4 times.. note: I don't need the whole program.. I just don't have any idea how a value is checked whether if it repeated itself three or more times.... help please....

Another approach: using System; class Program { static void Main() { int[] list = {4566786738797}; Array.Sort(list); int current = list[0]; int count = 1; for(int i = 1; i { if (list[i] == current) { count++; if (i } if (count >= 3) { Console.WriteLine(The value {0} is repeated {1} times current count); } current = list[i]; count = 1; } Console.ReadKey(); } }

Its because your return statement is inside if block. So What will it return if its else? So you need to have generic return statement at the end of program after if block or create else block and return something.

string[] list=new list{4566786738797}; foreach (int item in list) { Console.Write(item.ToString() + is repeated ); int count = 0; for (int i = 0; i { if (list[i] == item) ++count; } Console.WriteLine(count.ToString()+ times); }

Just check this class Program { static void Main(string[] args) { int[] list = new int[] { 4 5 6 6 7 8 6 7 3 8 7 9 7 }; var result = list.GroupBy(x => x).Where(x => x.Count() >= 3).Select(x => new { x.Key count = x.Count() }); foreach (var item in result) { Console.WriteLine(item.Key +  is repeated  + item.count +  times); } } }

This handle the problem: string kontrolet(string[] a) { string s = ; foreach (string item in a) { int sayici = 0; for (int i = 0; i { if (item == a[i]) { sayici++; } } if (sayici == 2) { s=Elinizde bir ikili var.; } if (sayici == 3) { s = Elinizde bir üçlü var.; } if (sayici == 4) { s = Elinizde bir dörtlü var.; } if (sayici == 5) { s = Elinizde bir besli var.; } } return s; } Thank you!

Hello. I wrote a function: string kontrolet(string[] a) { Array.Sort(a); int sayici = 0; string degisken = a[0]; for (int i = 1; i { if (a[i] == degisken) { sayici++; if (i { continue; } if (sayici > 2) { return You have got triple value.; } degisken = a[i]; sayici= 1; }}} it says not all part of the code returns a value.... what can I do...
