I Have a string Like "nitin" Write to method or logic to get output like n=2 i=2 t=1

using linq. class Program { static void Main(string[] args) { //int cnt = 0; int occ = 0; Console.WriteLine("Enter string"); string str = Console.ReadLine(); char[] newstr = str.Distinct().ToArray(); for (int i = 0; i < newstr.Length; i ) { Console.WriteLine(" {0} = {1} ", newstr[i], str.Count(x => x == newstr[i])); } Console.ReadLine(); } }

string str = "nitin"; var Mylsit = str.GroupBy(e => e).Select(g => new { g.Key, Count = g.Count() }).ToList(); Console.WriteLine(Mylsit[0]); Console.WriteLine(Mylsit[1]); Console.WriteLine(Mylsit[2]);

// For basic understanding (code tested) string str = "nitin"; int dynLength = str.Length; int i = 0, j = 1, c = 0; ; for (i = 0; i <= dynLength; i++) { for (j = 0; j < str.Length; j++) { if(str[0] == str[j]) // determining the occurances { c = c + 1; } } Console.WriteLine(str[0] + " : " + c); // print the character with no. of occurances str = str.Replace(str[0].ToString(),""); // remove character which is already counted; dynLength = str.Length; // set dynamic length after remove counted character c = 0; i = 0; } Console.ReadLine();

string input = "nitin"; var resultList = input.GroupBy(e => e).Select(g => new { g.Key, Count = g.Count() }).ToList();
