Convert infix to postfix
kvv77 [185]

Answer:

static int checkSymbol(char ch)

{

switch (ch)

{

case '+':

case '-':

return 1;

case '*':

case '/':

return 2;

case '^':

return 3;

}

return -1;

}

static String convertInfixToPostfix(String expression)

{

String calculation = new String("");

Stack<Character> operands = new Stack<>();

Stack<Character> operators = new Stack<>();

 

for (int i = 0; i<expression.length(); ++i)

{

char c = expression.charAt(i);

if (Character.isLetterOrDigit(c))

operands.push(c);

else if (c == '(')

operators.push(c);

 

else if (c == ')')

{

while (!operators.isEmpty() && operators.peek() != '(')

operands.push(operators.pop());

 

if (!operators.isEmpty() && operators.peek() != '(')

return NULL;    

else

operators.pop();

}

else

{

while (!operators.isEmpty() && checkSymbol(c) <= checkSymbol(operators.peek()))

operands.push(operators.pop());

operators.push(c);

}

}

while (!operators.isEmpty())

operands.push(operators.pop());

while (!operands.isEmpty())

calculation+=operands.pop();

calculation=calculation.reverse();

return calculation;

}

Explanation:

  • Create the checkSymbol function to see what symbol is being passed to the stack.
  • Create the convertInfixToPostfix function that keeps track of the operands and the operators stack.
  • Use conditional statements to check whether the character being passed is a letter, digit, symbol or a bracket.
  • While the operators is  not empty, keep pushing the character to the operators stack.
  • At last reverse and return the calculation which has all the results.

You've just installed a new video card in a user's Windows workstation. When the system is powered on the screen is blank. You
valentinak56 [21]

After having verified that the video cable is installed correctly we should check to see that the computer's RAM is correctly fastened to the motherboard and functional.

The question states that the video card being installed is new, therefore we can comfortably assume that the card itself is not the issue. Other computer components that can cause a blank screen immediately upon powering on the workstation are:

  • RAM
  • Hard drive
  • Bad video driver.
  • Monitor input is faulty

however, assuming the installation was performed correctly, it is not likely to be caused by a bad video driver and a faulty monitor input is very improbable given that there are very few ways this can break to begin with.

A bad or missing hard drive may cause this kind of issue because the workstation will not have a windows file to boot. In most cases, this will not cause a completely blank screen without first allowing access to the BIOS.

After having verified that the video cable is installed correctly, the very next thing you should check is if the RAM is installed correctly. This is because the issue explained is exactly what will happen if a workstation attempts to boot without RAM, and also because it is the easiest fix among the possible causes and any troubleshooting should always be performed in order from the easiest fix to the most difficult.
