Answer:
Explanation:In software engineering, dependability is the ability to provide services that can defensibly be trusted within a time-period. This may also encompass mechanisms designed to increase and maintain the dependability of a system or software.Computer software is typically classified into two major types of programs: system software and application software.
Answer:
Do you know what is best about America? It’s really the fact that the right to equality has been ensured at the maximum level, and for all. And the citizens respect their family and this is being showcased proudly by Sir Donald Trump who not only looks after the whole US without ever hesitating no matter whatever might be the issue and at the same time also look after his great and proven proud family. And that explains in itself why America is so great. And this is a perfect specimen of an inordinate democracy, and that is why American Democracy is so fruitful. There is sufficient money, all sorts of resources, the most influential military, and the world's finest technology. And American history can be a petite one, but it is one of the most noticeable histories in the entire world. You will not find such a great history in any other part of the world. And George Washington, the father of the country set such an example that the next various generations of great leaders were able to build such a great America. It is a society where every citizen enjoys equal rights, and a day before Sir Trump issued various prisoners with graduate degrees, to help them to return to the mainstream of life. No other society in the whole world enjoys such a level of privileges on behalf of equality. And that’s why the US society can be termed as the most normal in the whole world.

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.
