05. Digits, Letters and Other
Write a program that receives a single string and on the first line prints all the digits, on the second – all the letters, and on the third – all the other characters. There will always be at least one digit, one letter and one other characters.
Examples
Input                 Output
Agd#53Dfg^&4F53       53453
                      AgdDfgF
                      #^&
Hints
• Read the input.
• Use loop to iterate through all characters in the text. If the char is digit print it, otherwise ignore it.
o   Use char.IsDigit(char symbol)
• Do the same for the letters and other chars
o   Find something like IsDigit method for the letters.
