what is at the top of the stack after the following operations are run? push(4) push(12) pop() push(26)
Answers
20,20,10,10,20 will be at the top of the stack after the given operations are run.
What is stack?A set of related elements is grouped together logically as a stack. In programming and computer memory management, the phrase is frequently used.
Last in first out (LIFO), a type of data abstraction that is frequently used and is composed of the two main operations push and pop, is the foundation of programming stacks. In contrast to the pop operation, which removes elements from the top position, the push operation adds elements to the stack's bottom position.
The top position is tracked using a variable or header pointer, respectively, in arrays and linked lists, which are used to implement the stack concept in software. For the implementation of stacks, many programming languages have built-in features.

What is a bubble sort?Bubble sort, commonly referred to as sinking sort, is a basic sorting algorithm that continually moves through the input list element by element, comparing the current element with the one following it, exchanging their values if needed.
The term "responsibility" refers to the act of determining whether or not a person is responsible for his or her own actions. Just to the movement of air bubbles in the water that rise up to the surface, each element of the array migrate to the end in each iteration. As a result, it is known as a bubble sort.
One of the primary benefits of a bubble sort is that it is a simple algorithm to describe to a computer. There is just one duty to do (compare two values and, if needed, swap them). This results in a very tiny and straightforward computer application.

HYUNDAI Motors is considering producing cars in Incheon with production function Q=10KL
2
, where Q is number of cars per week, K is units of capital measured in automated assembly-lines, and L is thousands of workers per week. SAMSUNG Motors is considering producing cars in Daegu with production function Q=10 K
2
L. A) Both HYUNDAI and SAMSUNG must pay ∀600,000,000 per unit of labor ( W600,000 per worker x1,000 workers) and W1,200,000,000 per unit of capital, where W600,000 is the weekly wage and W1,200,000,000 is the weekly interest cost to finance an automated assembly line. How many units of labor and how many units of capital would each firm use to produce 1280 cars? (You may round your answer to the nearest 1,000 workers and the nearest automated assembly line.) B) How much would it cost HYUNDAI to produce 1280 cars? What would the cost be per car? C) How much would it cost SAMSUNG to produce 1280 cars? What would the cost be per car? D) While the firms are studying their options, BOK doubles interest rates up so that the cost of capital rises to W2,400,000,000. The Incheon economy is booming, and HYUNDAI finds that it must pay $1,200,000 per worker per week. Daegu's economy is less vibrant, and wage per worker stay at W600,000 per week. How many units of labor and how many units of capital will each firm now envision needing to produce 1280 cars? What are each firm's prospective costs per car?
Answers
A)19,261 units of labor and 32 units of capital. B)The cost of HYUNDAI is V38,020,800,000, resulting in a cost per car of V29,690,625. C)25,398 units of labor and 40 units of capital. D)V52,463,200,000
If the interest rates double and Hyundai has to pay $1,200,000 per worker per week while Samsung's wage per worker remains at W600,000 per week, Hyundai would require around 9,219 units of labor and 45 units of capital. The prospective cost for Hyundai per car would increase to V41,570,313. Samsung, in this scenario, would need approximately 12,199 units of labor and 50 units of capital. The prospective cost for Samsung per car would be V44,385,938.
A) To find out the number of units of labor and capital required by Hyundai and Samsung to produce 1280 cars, we can use their respective production functions. For Hyundai, Q = 10KL^2, where Q is the number of cars, K is the capital (automated assembly lines), and L is the labor. By substituting Q = 1280, we can solve for K and L. Similarly, for Samsung, Q = 10K^2L. By substituting Q = 1280, we can solve for K and L. Rounding the values to the nearest thousand workers and automated assembly lines gives us the final results.
B) To calculate the cost for Hyundai to produce 1280 cars, we multiply the number of units of labor by the wage per worker and the number of units of capital by the interest cost per assembly line. Adding these costs together gives us the total cost for Hyundai. Dividing the total cost by the number of cars (1280) provides us with the cost per car.
C) The process for calculating the cost for Samsung is similar to that of Hyundai. We multiply the number of units of labor by the wage per worker and the number of units of capital by the interest cost per assembly line. Adding these costs together gives us the total cost for Samsung. Dividing the total cost by the number of cars (1280) provides us with the cost per car.D) In this scenario, the interest rates double, and Hyundai has to pay $1,200,000 per worker per week, while Samsung's wage per worker remains at W600,000 per week. We repeat the calculations using the new wage and interest rate values to determine the number of units of labor and capital required by each firm. The prospective cost per car is then calculated using the same method as in parts B and C, but with the updated costs.

A(n) _______________ reference is a cell reference whose location remains constant when the formula is copied.
Answers
A "absolute" reference is a cell reference whose location remains constant when the formula is copied.
In spreadsheet software such as Microsoft Excel, cell references are used in formulas to perform calculations based on the values in different cells. By default, when a formula is copied to other cells, the references within the formula are adjusted relative to the new location. However, an absolute reference is a type of cell reference that remains fixed or constant when the formula is copied. It is denoted by using a dollar sign ($) before the column letter and/or row number. For example, "$A$1" represents an absolute reference to cell A1.
When a formula contains an absolute reference, the referenced cell remains the same regardless of where the formula is copied or filled. This allows users to refer to a specific cell or range of cells consistently, even when the formula is used in different locations. Absolute references are particularly useful when working with formulas that need to reference specific cells or when creating calculations that should not change their reference when copied to different locations within a spreadsheet.

The type of structure in which one step follows another unconditionally is called a "sequence structure".

Each step in the sequence is executed unconditionally, meaning that it will always be executed, regardless of any other conditions or inputs.

In programming terms, a group of characters inside a set of double quotation marks (" ") is called a string literal.
A string literal can include any combination of letters, numbers, symbols, and white spaces, and is used to represent text-based data in computer programs. The string literal is a fundamental data type in many programming languages, including Java, Python, C++, and JavaScript. It is often used to store user input, output messages, file names, and other types of data that involve text.
When a program encounters a string literal, it treats it as a single entity and performs various operations on it, such as concatenation, comparison, and manipulation. So, in summary, a string literal is a sequence of characters enclosed in double quotation marks that represents text data in programming languages.

The voltage or current cycle's shape is described by the waveform. Bipolar current is a type of alternating current (AC) in which the flow of current alternates between positive and negative directions around zero.
Thus, An alternative is a direct current (DC), which has a single direction of flow (unipolarity), either positive or negative.
DC currents are frequently pulsed (pDC), which means that during a portion of the cycle duration, the current is stopped (at zero amplitude).
The mark space ratio (where the mark is the time the current is 'on' and the space is the time the current is 'off', i.e. at zero) can be used to describe the resulting waveform.
