C# program which accept one string and one integer?

Question

If string=aabbccc and Int 2 output=ccc ......It will remove aabb as their count match with enter int. If string=aaabbccc and Int 3 output=bb If string=aaabbccc and Int 1 output=aaabbccc output will be same as none of the character match with entered string. If string=abc Int 1 output= output will be empty as the as all character matched with entered string

We can achieve this by using LINQ as follows, public static void RemoveChars( string str, int count) { try { //group the string based on character and filter those with the passed integer value var lst = str.ToCharArray().ToList().GroupBy(p => p).Select(a => new { key = a.Key, cnt = a.Count() }).Where(q => q.cnt != count).Select(c => c.key).ToList(); //filter the remaining charter value from passing string and get the array var r = str.ToCharArray().Where(p => lst.Contains(p)).ToArray(); //print string from result char array Console.WriteLine( new string (r)); } catch { throw ; } }

static void removeduplicate( string str, int opt) { string s = "" ; char [] chrs = str.ToArray(); if (opt == 3) { for ( int i = 0; i { if ((i { if ((chrs[i] == chrs[i + 1] && chrs[i] == chrs[i + 2])) { i = i + 2; } else { s += chrs[i]; } } else { s += chrs[i]; } } Console.WriteLine(s); } }
