Linked lists and arrays differ in terms of memory allocation, insertion/deletion efficiency, and random access.

• Arrays have contiguous memory allocation, while linked lists have non-contiguous memory allocation.

• Arrays have constant time access to elements, while linked lists have linear time access.

• Linked lists are more efficient for insertion/deletion operations, as they do not require shifting elements like arrays.

• Arrays are better for random access, as elements can be acces...read more

Sorting in C language refers to arranging elements in a specific order.

• C language provides various sorting algorithms like bubble sort, insertion sort, selection sort, merge sort, quick sort, etc.

• Sorting can be performed on arrays, linked lists, or other data structures.

• The standard library function 'qsort' can be used for sorting arrays in C.

• Sorting can be done in ascending or descending order based on the comparison function provided.

The output will be 'Hello' as the condition 'if(a)' will evaluate to true since 'a' is not equal to 0.

• The condition 'if(a)' will evaluate to true if 'a' is not equal to 0.

• In this case, 'a' is equal to 8 which is not equal to 0, so 'Hello' will be printed.

The program will print numbers from 1 to 5 continuously without spaces.

• The for loop increments i by 1 each iteration

• The printf statement prints the value of i without a newline character

• The loop continues until i is greater than 5

• MAX function is used to find the highest value in a range of cells.

• Syntax: =MAX(number1, [number2], ...)

• Example: =MAX(A1:A10) will return the highest value in cells A1 to A10.

HLOOKUP and VLOOKUP are Excel functions used to search for specific data in a table and return related information.

• HLOOKUP searches for data in a row and returns information from a specific column.

• VLOOKUP searches for data in a column and returns information from a specific row.

• Both functions require a lookup value, a table array, a column or row index number, and an optional range lookup value.

• These functions are commonly used in data analysis and reporting.

• Example: VLOOKUP ...read more

Banker's algorithm is a resource allocation and deadlock avoidance algorithm used in operating systems.

• Used to avoid deadlock in a system by ensuring that resources are allocated safely

• Consists of multiple algorithms including safety algorithm and resource request algorithm

• Requires information about available resources, maximum resources, allocated resources, and need of each process

• Example: If a process requests additional resources, the banker's algorithm checks if the syst...read more
