Given a string str, divide the string into three parts one containing a numeric part, one containing alphabetic and one containing special characters.
Examples:
Input : geeks01for02geeks03!!!
Output :geeksforgeeks
010203
!!!
Here str = "Geeks01for02Geeks03!!!", we scan every character and
append in res1, res2 and res3 string accordingly.
Input : **Docoding123456789everyday##
Output :Docodingeveryday
123456789
**##
Steps :
- Calculate the length of the string.
- Scan each every character(ch) of a string one by one
- if (ch is a digit) then append it in res1 string.
- else if (ch is alphabet) append in string res2.
- else append in string res3.
- Print the all the strings, we will have one string containing numeric part, other non numeric part and last one contain special characters.

C#
// C# program to split an alphanumeric // string using stringbuffer using System; using System.Text; class GFG { // Function ot split string static void splitString(string str) { StringBuilder alpha = new StringBuilder(); StringBuilder num = new StringBuilder(); StringBuilder special = new StringBuilder(); for (int i = 0; i < str.Length; i++) { if (Char.IsDigit(str[i])) num.Append(str[i]); else if((str[i] >= 'A' && str[i] <= 'Z') || (str[i] >= 'a' && str[i] <= 'z')) alpha.Append(str[i]); else special.Append(str[i]); } Console.WriteLine(alpha); Console.WriteLine(num); Console.WriteLine(special); } // Driver code public static void Main() { string str = "geeks01$$for02geeks03!@!!"; splitString(str); } } // This code is contributed by Sam007 |
Output:
geeksforgeeks 010203 $$!@!!
Time complexity of above solution is O(n) where n is the length of the string.
