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.
The option that can be used to identify and analyze which characteristic of OSPF signifies this is known to be Low overhead, fast convergence.
<h3>What is OSPF about?</h3>
The OSPF is known to be called an open Shortest Path First protocol.
It belongs to the family of IP Routing protocols as it serves as Interior Gateway Protocol (IGP) used mainly for the Internet, and the option that can be used to identify and analyze which characteristic of OSPF signifies this is known to be Low overhead, fast convergence.
See full question below
A network administrator has asked Robin, a network engineer, to use OSPF (Open Shortest Path First) along with RIP (Routing Information Protocol) on an edge router in a network so that it demands more memory and CPU power for calculations but keeps network bandwidth to a minimum with a very fast convergence time. Identify and analyze which characteristic of OSPF signifies this.

Answer:
Negative transfer of learning
Explanation:
Negative transfer of learning occur when the knowledge you've acquired in the past is/are interfering with the one(s) you are currently acquiring.
Example: learning a new language that have some differences in pronunciation from the previous one, changing from a right-sided vehicles to a left-sided vehicles etc.
