4. Evaluate the Alternatives

Weigh the pros and cons of each solution.

Assess feasibility, costs,

Q1. What are the common performance issues that can occur in a system?
Ans. 
Common performance issues in a system include slow response times, high resource usage, bottlenecks, and crashes.
• Slow response times can be caused by inefficient code, network latency, or overloaded servers.

• High resource usage can lead to system slowdowns and crashes, often caused by memory leaks or inefficient algorithms.

• Bottlenecks occur when a component of the system becomes a limiting factor, such as a database ser...read more

Shortcut Tips for Coding Tests: 1. Master the Basics: Familiarize yourself with arrays, strings, loops, and conditional statements. 2. Learn Patterns: Concentrate on sliding window, two-pointer techniques, recursion, and divide-and-conquer methods. 3. Use Standard Algorithms: Study breadth-first search (BFS), depth-first search (DFS), sorting algorithms, and dynamic programming principles. 4. Understand Data Structures: Practice with stacks, queues, linked lists, and trees. 5. Practice Edge Cases: Consider scenarios involving empty inputs, duplicates, and large datasets. 6. Write Pseudocode: Outline your plan before starting to code. 7. Optimize Early: Always strive for efficiency in your solutions.

Q3. What is recursion, write a code for it
Ans. 
Recursion is a programming technique where a function calls itself to solve a problem.
• Recursion involves breaking down a problem into smaller subproblems and solving them recursively.

• A base case is needed to stop the recursion and prevent infinite loops.

• Example: Factorial calculation using recursion - function factorial(n) { return n === 0 ? 1 : n * factorial(n-1); }

Q4. Why we don't use pointers in java
Ans. 
Java doesn't use pointers for security and simplicity reasons.
• Java uses references instead of pointers to avoid direct memory manipulation.

• Pointers can lead to memory leaks and security vulnerabilities.

• Java's garbage collection manages memory automatically, reducing the need for pointers.
