Th interviewer asked me questions related to various topics of OS, Data Structures and Algorithm.
Tips: Have a strong hold on topics of OS like segmentation and buddy systems.
Segmentation is the process of dividing a larger entity into smaller parts or segments.
Segmentation is commonly used in image processing to separate objects of interest from the background.
It is also used in marketing to divide a target market into smaller groups based on demographics, behavior, or other factors.
In networking, segmentation refers to dividing a network into smaller subnetworks to improve performance and
The buddy system has advantages like increased safety and support, but also drawbacks like dependency and lack of independence.
Advantages: increased safety, support, accountability, motivation
Disadvantages: dependency, lack of independence, potential for conflicts
Example: In a buddy system at work, colleagues can support each other in completing tasks and provide motivation to stay on track.
Example: However, relying to...

A min-binary heap is a complete binary tree where each internal node's va...
Convert the given array into a min-binary heap by modifying the array elements.
Iterate through the array and heapify each node starting from the last non-leaf node to the root node.
For each node, compare it with its children and swap if necessary to satisfy the min-heap property.
Continue this process until the entire array is converted into a min-heap.
