The tombstone approach involves setting a "tombstone" value to indicate that an object has been deleted.

The tombstone approach is a method for dealing with dangling pointers, which occur when a pointer refers to an object that has been deleted or deallocated.

When an object is deleted, a "tombstone" value is placed in its memory location to indicate that it has been deleted.

Any dangling pointers that refer to the deleted object are then updated to point to the tombstone value.

When a program attempts to use a dangling pointer that has been updated with a tombstone value, an error will occur, preventing the program from accessing the deleted object.

The tombstone approach helps to prevent memory access errors and improve the stability and reliability of software systems that use pointers.

The kind of circuit that selects binary information from one of many input lines and directs it to a single output line is called a multiplexer (also known as a MUX).

A Multiplexer (MUX) is the kind of circuit that selects binary information from one of many input lines and directs it to a single output line. It acts as a switch that chooses the desired input based on a selection code provided to it. It is a gadget that chooses between a few simple or computerized input signals and advances the chosen contribution to a solitary result line. A separate set of digital inputs known as select lines direct the selection. This combinational circuit can have up to n data inputs, n selection lines, and a single output line. The values of the selection lines will be used to connect one of these data inputs to the output. There will be a total of n possible zero-to-one combinations because there are n selection lines.

The Array.prototype.reduceRight() method in JavaScript is used to apply a callback function to each element of an array and return a single accumulated value.

The callback function takes four parameters - accumulator (the accumulated result), currentValue (the current element being processed), currentIndex (the index of the current element), and the original array.

The reduceRight() method works similarly to reduce(), but it processes the array from right to left instead of from left to right.

The optional initialValue parameter sets the initial value of the accumulator. If it is not provided, the last element of the array is used as the initial value.

Here is an example of using reduceRight() to find the sum of all the elements in an array:

const numbers = [1, 2, 3, 4, 5];
const sum = numbers.reduceRight((accumulator, currentValue) => accumulator + currentValue, 0);
console.log(sum); // outputs 15

Using find Max() decreases the redundant code of the given code. The correct answer is b.

How does using find Max() improve the code?

By using the findMax() method, we are able to avoid repeating the same if-else statement multiple times throughout our code. This results in cleaner, more concise code and reduces the chances of errors or inconsistencies in our comparisons. Additionally, it allows us to easily make changes to our max-finding logic in one centralized location if needed. However, using findMax() does not necessarily improve the speed of our code or reduce the number of variables needed. Using findMax() improves the code by decreasing redundant code. The findMax() function allows you to compare two values and return the maximum value without repeating the comparison code in multiple places within the main() function. This makes the code more efficient and easier to maintain.

So, the correct answer is b. Using find Max() decreases redundant code.

Overflow is a situation that occurs when a mathematical operation produces a result that exceeds the maximum value that can be represented by a given number of bits.

Overflow can be detected by examining the most significant bit of the result. If the most significant bit is 1, then overflow has occurred. In unsigned numbers, overflow occurs when the result is too large to be represented by the number of bits used to store the value. In signed numbers, overflow occurs when the result is too large or too small to be represented by the number of bits used to store the value. This is because signed numbers use one bit to represent the sign, reducing the number of bits available to represent the magnitude of the number. To detect overflow in signed numbers, the most significant bit and the sign bit are examined. If the sign bit and the most significant bit are different, then overflow has occurred.

In part (a), an inverting amplifier with a gain of 4 can be designed using an ideal op amp, a resistor in the feedback path, and 12 V power supplies.

The circuit diagram of an inverting amplifier consists of an input voltage source, a feedback resistor, and an output voltage source. To achieve a gain of 4, the feedback resistor should be three times the value of the input resistor.

Therefore, a suitable value for the feedback resistor would be 3kΩ and the input resistor should be 750Ω.

In part (b), the range of input voltages that will keep the op amp in its linear operating region can be determined by analyzing the output voltage range.

The op amp will remain in its linear operating region as long as the output voltage stays within the range of the power supplies. In this case, the power supplies are ±12 V.

Therefore, the input voltage range can be calculated by dividing the output voltage range by the gain of the amplifier, which is 4. So, the input voltage range should be within ±3 V to keep the op amp in its linear operating region.
