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.

Convert the following MIPS instruction to its binary and hex representations by doing the following: On first line, type registe

Firdavs [7]

Answer:

To make the group of four we can write 100011 as 00100011

Now, the two groups are:- 0010 and 0011

And 0010 in binary corresponds to 3 in Hexadecimal

And 0011 in binary corresponds to 4 in Hexadecimal.

So, 100011 of binary corresponds to 34 of hex.
