Data frames are a data structure used for storing and manipulating tabular data in R programming language. Assembly language is a low-level programming language that is used to write programs that can directly interact with the hardware of a computer. Dynamic programming is a technique used to solve complex problems by breaking them down into smaller subproblems and solving them recursively.

The time complexity of swap array program is O(n).

• The time complexity is determined by the number of elements in the array.

• The program swaps the elements of the array one by one, so it takes linear time.

• The Big O notation for the time complexity is O(n), where n is the number of elements in the array.

• Examples: swapping two elements in an array takes constant time, but swapping all elements takes linear time.
