C++ program to reverse a string

• Use a loop to iterate through the string

• Swap the characters at the beginning and end of the string

• Continue swapping until the middle of the string is reached

Single linked list has one pointer while doubly linked list has two. Doubly linked list is preferred for easier traversal in both directions.

• Single linked list has only one pointer which points to the next node while doubly linked list has two pointers which point to the next and previous nodes.

• Doubly linked list allows for easier traversal in both directions, while single linked list only allows for traversal in one d...read more

LINUX/UNIX are open-source, command-line based OS while WINDOWS is a proprietary, GUI-based OS.

Program to sort an array of strings

• Use a sorting algorithm like bubble sort, insertion sort, or quicksort

• Compare adjacent elements and swap if necessary

• Repeat until the array is sorted

Sorting techniques and their time complexity

• Bubble sort - O(n^2)

• Selection sort - O(n^2)

• Insertion sort - O(n^2)

• Merge sort - O(n log n)

• Quick sort - O(n log n)

• Heap sort - O(n log n)

• Radix sort - O(nk)

• Most efficient: Quick sort or Merge sort

• Efficiency depends on the size of the array and the data distribution

Big data refers to large and complex data sets that cannot be processed using traditional data processing methods.
