Stack is LIFO and Queue is FIFO data structure. Stack is like a stack of plates and Queue is like a queue of people.
Stack is Last In First Out (LIFO) and Queue is First In First Out (FIFO)
Stack is like a stack of plates where the last plate added is the first one to be removed
Queue is like a queue of people where the first person to enter is the first one to leave
Stack is used in undo-redo functionality in text editors
It depends on the use case. QuickSort is generally the fastest, but MergeSort is more stable and efficient for larger datasets.
QuickSort is generally the fastest sorting algorithm, but can be unstable for certain datasets.
MergeSort is more stable and efficient for larger datasets, but can be slower than QuickSort for smaller datasets.
InsertionSort is efficient for small datasets, but can be slow for larger datasets.

Semaphore and mutex are synchronization mechanisms used in multi-threaded environments.
Semaphore allows multiple threads to access a shared resource simultaneously, while mutex allows only one thread at a time.
Semaphore is used to control access to a pool of resources, while mutex is used to protect a single resource.
Semaphore uses a counter to keep track of the number of available resources, while mutex uses a lock to...
Find the repeating number in an array.
Iterate through the array and store each element in a hash table or set.
If an element is already present in the hash table, it is a repeating number.
Alternatively, sort the array and check for adjacent elements with the same value.
Time complexity: O(n) or O(nlogn) depending on the approach used.
Paging and segmentation are memory management techniques used by operating systems.
Paging divides memory into fixed-size pages and stores data in these pages.
Segmentation divides memory into logical segments and stores data in these segments.
Paging is simpler and more efficient, but can lead to external fragmentation.
Segmentation is more flexible, but can lead to internal fragmentation.
Both techniques are used to manag
