Algorithm Complexity and Data Structure Fundamentals Q&A
1. What is recurrence for worst case of QuickSort and what is the time complexity in Worst case?
Recurrence is T(n) = T(n-1) + O(n) and time complexity is O(n^2)
2. Suppose we have a O(n)
time algorithm that finds median of an unsorted array. Now consider a QuickSort implementation where we first find median using the above algorithm, then use median as pivot. What will be the worst case time complexity of this modified QuickSort.
O(nLogn)
3. Given an unsorted array. The array has this property

C Operators and Expressions Fundamentals
Understanding C operators and expressions is crucial. This section details the different types of operators, their hierarchy, and expression evaluation rules.
Operators and Expressions Defined
An operator is a symbol that instructs the compiler to perform specific mathematical or logical manipulations. An expression is a combination of operators, constants, and variables that resolves to a single value.
1. Primary Operator Types
A. Arithmetic Operators
These are

Climate Change, Global Warming and the Greenhouse Effect
The concepts of climate change, global warming, the greenhouse effect, and ozone depletion are fundamental to understanding the current state of our global environment and the imperative for sustainable development.
🌡️ Climate Change and Global Warming
Climate change refers to a long-term shift in the average weather conditions of a region or the Earth as a whole. This includes changes in temperature, precipitation patterns, and wind patterns.

Modernism in Hispanic Literature
Modernism: In the late nineteenth century, this movement emerged from a general crisis since people lost confidence in progress, and it was reflected in artistic and cultural development within the field known as modernismo in the Hispanic world.
Modernism: ‘I represent a vital attitude of artists who reacted against bourgeois utilitarianism.’ Born in Hispanic America, this rejection also joined a rejection of imperialism.

Fundamentals of Human Resource Management
Human Resource Management (HRM) is the strategic approach to managing people in an organization to achieve both individual and organizational goals. It involves recruiting, selecting, training, developing, motivating, and retaining employees while ensuring their well-being and growth. HRM views employees as valuable assets whose skills and performance are crucial for organizational success.
Definition: According to Dale Yoder, HRM is “the planning, organizing, directing, and controlling of the

Wheat Stem Borer (S. inferens)
Systematic Position
- Class: Insecta
- Order: Lepidoptera
- Family: Noctuidae
Habits
The wheat stem borer is a nocturnal insect, living for 10–15 days. Eggs are laid on the inner surface of the host plant’s leaf sheath. Caterpillars bore into the stems of the wheat plant to feed. The caterpillar prefers moist weather to infest new shoots.
Damage
The caterpillars attack and destroy young shoots of the wheat crop, causing uneven growth. The central shoot is damaged completely, resulting

Human Resource Planning (HRP)
Human Resource Planning (HRP) is the process of anticipating and making provisions for the movement of people into, within, and out of an organization. It helps in aligning human resources with the organization’s goals.
Benefits of HR Planning
- Optimum Utilization of Human Resources: Prevents overstaffing or understaffing.
- Better Recruitment and Selection: Supports proactive hiring strategies.
- Improved Employee Development: Identifies training and development needs.
- Succession
Software Testing Concepts: STLC, Bug Life Cycle & Metrics
Input Domain Testing
The input domain of a program is the set of all possible inputs that it can accept. Since testing every single input is impossible, input domain testing is used to partition the input space into manageable subsets, ensuring effective test coverage.
Explanation:
- Input domain testing is a black-box testing technique.
- Inputs are divided into equivalence classes (valid and invalid).
- Testers choose representative values from each class.
- Special focus is given to boundary values, since

Flip-Flop Characteristic Tables
The Characteristic Table summarizes the behavior of a flip-flop by listing the next state (Qn+1) for all possible combinations of the present state (Qn) and the input(s). It is derived directly from the operating rules of the flip-flop.
SR Flip-Flop Characteristics
| Present State (Qn) | Inputs (S, R) | Next State (Qn+1) | Operation |
|---|---|---|---|
| 0 | 0, 0 | 0 | Hold |
| 0 | 0, 1 | 0 | Reset |
| 0 | 1, 0 | 1 | Set |
| 0 | 1, 1 | X (Undefined) | Forbidden |

Money Market Instruments: Characteristics and Function
The term “Money Market” is somewhat of a misnomer. Currency itself is not traded; rather, the securities in the money markets are short-term with high liquidity, making them close substitutes for money.
Money Markets Defined
Key characteristics of money market securities include:
- Usually sold in large denominations (e.g., $1,000,000 or more).
- Low default risk.
- Mature in one year or less from their issue date, though most mature in less than 120 days.
Money Markets Versus Banks
