The question asks to fill the blanks in a pyramid where each number is the sum of the numbers in the bottom two cells.
Start from the bottom row and work your way up, calculating the sum of the numbers in the bottom two cells for each blank space.
Use a loop to iterate through each row and column of the pyramid.
Store the calculated sum in the corresponding blank space.
Repeat the process until all the blanks are filled.

Scheduling is the process of allocating resources to tasks based on priority and availability.
Different types of scheduling include: preemptive and non-preemptive scheduling, round-robin scheduling, priority scheduling, and deadline scheduling.
Preemptive scheduling allows higher priority tasks to interrupt lower priority tasks, while non-preemptive scheduling does not.
Round-robin scheduling allocates a fixed time slice...
A deadlock is a situation where two or more processes are unable to proceed because they are waiting for each other to release resources.
Deadlocks occur when two or more processes are blocked and unable to continue executing.
To detect a deadlock, look for circular wait, hold and wait, no preemption, and mutual exclusion.
Examples of deadlocks include a printer that is waiting for a user to replace the paper tray, or two...
Moore's Law is the observation that the number of transistors in a dense integrated circuit doubles about every two years.
Named after Intel co-founder Gordon Moore
First stated in 1965
Has been a driving force behind technological advancements
Predicts exponential growth in computing power
Has been challenged in recent years due to physical limitations
A process is an instance of a program while a thread is a subset of a process.
A process has its own memory space while threads share memory space
Processes are heavyweight while threads are lightweight
Processes communicate through inter-process communication while threads communicate through shared memory
Examples of processes include web browsers, text editors, etc. while examples of threads include GUI updates, backgro

Explain Big O notation
Big O notation is used to describe the time complexity of an algorithm
It helps us understand how the algorithm's performance changes with input size
O(1) means constant time, O(n) means linear time, O(n^2) means quadratic time
We want algorithms with lower Big O values for better performance
I am open to relocation based on the job opportunity and growth prospects.
Open to relocation for the right opportunity
Willing to move for career growth
Flexible with location based on job requirements
Yes, I would love to have a pizza slice!
I am a big fan of pizza and would never say no to a slice!
Pizza is the perfect food for any occasion, whether it's a quick lunch or a late-night snack.
I particularly enjoy pepperoni and mushroom pizza, but I'm open to trying new toppings as well.

Types of caching mechanisms include browser caching, server-side caching, and content delivery network (CDN) caching.
Browser caching: storing web page resources locally on a user's device to reduce load times on subsequent visits.
Server-side caching: storing data in memory on the server to reduce the need to fetch data from the database repeatedly.
Content Delivery Network (CDN) caching: caching content on servers distr...
Physical memory refers to the actual RAM installed in a computer, while virtual memory is a memory management technique that uses disk space as an extension of RAM.
Physical memory is the actual hardware component where data is stored temporarily for quick access by the CPU.
Virtual memory is a memory management technique that allows the operating system to use disk space as an extension of physical memory.

Qualcomm interview questions for designations
Detect endianness using C program
Use a union to create a variable with a known value
Check the value of the first byte to determine endianness
Big endian systems store the most significant byte first
Little endian systems store the least significant byte first
Example: union { int i; char c; } u; u.i = 1; if (u.c == 1) { /* Little endian */ } else { /* Big endian */ }
Count set bits in a number using C programming language.
Use bitwise AND operation with 1 to check if the rightmost bit is set.
Shift the number to the right by 1 bit each time to check all bits.
Repeat the process until the number becomes 0, counting the set bits each time.

Volatile keyword in Java is used to indicate that a variable's value will be modified by multiple threads.
Volatile keyword ensures visibility of changes made by one thread to other threads.
It prevents compiler optimizations that could reorder code and cause unexpected behavior in multi-threaded environments.
Volatile keyword is used for variables accessed by multiple threads without synchronization.
Example: 'volatile in
Union is a data structure that allows storing different data types in the same memory location, while structure is a data structure that allows storing different data types in a single unit.
Union uses the same memory location for all its members, while structure allocates separate memory for each member.
In a union, only one member can be accessed at a time, while in a structure, all members can be accessed simultaneous...
