Question
Explain the bubble sort algorithm.
Answers
Bubble sort algorithm is used for sorting a list. It makes use of a temporary variable for swapping. It compares two numbers at a time and swaps them if they are in wrong order. This process is repeated until no swapping is needed. The algorithm is very inefficient if the list is long.

E.g. List: - 7 4 5 3
1. 7 and 4 are compared

2. Since 4 < 7, 4 is stored in a temporary variable.

3. the content of 7 is now stored in the variable which was holding 4

4. Now, the content of temporary variable and the variable previously holding 7 are swapped.   Your Comment
