1)if the result is not 0, double the result and use it as the first number and repeat step 1.

For example :

let us consider 7 , 8 as inputs
step 1 :
7 * 2 - 8 = 6, which is not zero, so it goes to next step and first number is 6
6 * 2 - 8 = 4, which is not zero, so it goes to next step and first number is 4
4 * 2 - 8 = 0, here it satisfies the condition so system will print 7 , 8

Another sample set that satisfies the above condition: 10, 20
10 * 2 - 20 = 0, here it satisfies the condition so system will print 10 , 20

2)lmplement a function by reading one string from keyboard
And that string must have for every opening parenthesis it must be close with corresponding parenthesis.
Example 1:((hai hello ) all the (best))
It should return true.
Example 2: ())(
It should return false.

//Program 1
//Inputs: First variable should be less than second variable. If its not then it's false
public void Output(int var1, int var2)
{
   if(var1 < var2)
   {
       bool returnValue = RecursiveOut(var1, var2);
       if(returnValue == true)
       {
           Console.WriteLine("Display Inputs: " + var1 + "," + var2);
       }
   }
}

public bool RecursiveOut(var1, var2)
{
   if(var1 > 0)
   {
       var1 = var1*2 - var2;
       if(var1 == 0)
       {
           return true;
       }
       return RecursiveOut(var1, var2);
   }
   return false;
}

//Program 2
//use stack : push if open brace. Pop if close brace.
//At the end of string the stack should be empty to statisfy the operation

public bool ParseString()
{
   string str1 = Console.ReadLine();
   Stack stack = new Stack();

   if(line != null)
   {
       foreach(character in str1.ToCharArray())
       {
           if(character == "(")
           {
               stack.Push("(");
           }
           else if(character == ")")
           {
               stack.Pop();
           }
       }

       if(stack.Count == 0)
       {
           return true;

   return false;

Question 1:

int isSatisfy = checkAll(0, 0); // If it is 1 then satisfied otherwise not satisfied.

public static int checkAll(int result, int ckecker)
{
   if(result > 0)
   {
         int tempVal = result * 2 - ckecker;
         if (tempVal == 0)
         {
            return 1;
         }
         return checkAll(tempVal, ckecker);
    }
   return 0;
}

Question 2:

string tempStr = "((hai hello ) all the (best))";

int counter1 = (from p in tempStr
where p == '('
select p).Count();

int counter2 = (from p in tempStr
where p == ')'
select p).Count();

if (counter1 == counter2)
{
   Console.WriteLine("True");
}
else
{
   Console.WriteLine("False");
}
