CSharp22Ex01

  1. write a program that read 3, 7-bit numbers (include input validation), parsing the input to decimal numbers (not using the c# built-in function), print them in increased order , how many palindrome? , how many devided by 3?, how many ones/zeros?, what is the total 3 avarage of decimal digits?.

  2. write a program that print this exct shape using recurssion

         '''
          *
         ***
        *****
       *******
      *********
       *******
        *****
         ***
          *
         '''
    
  3. write a program that print the Diamond from question 2 but in every height the user ask (include input validation) try use the assembly from question 2.

4.write a program that the input a 9 char string and give the following feedback:

  4.1 is the string is palindrome?
  4.2 if it's a number - is it devided by 3?
  4.3 if it's an eanglish letter only string , how many of them are small letters?
  4.4 pay attention to user input , it should contain only eanglish letters *or* only numbers -> input validation.

5.write a program that read 9 digit wholw number and gives the following feedback:

	5.1 how many digits are smaller than the unit digit? 
	5.2 what is the biggest digit according to user input? 
	5.3 how many numbers divided by 3 ? 
	5.4 what is the mean sum of digits ?
	
	000000123 is also a number . require input validation.
