Question

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 { 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); }
