Recursion is used to find the permutations of a string yup.

• The if condition prints string passed as argument if it is equal to the length of yub.
• In each iteration of the for loop, each character of yup is stored in words.
• The elements of words are swapped. In this way, we achieve all different combinations of characters.

• The divmod() method takes two numbers and returns a pair of numbers (a tuple) consisting of their quotient and remainder.
• end='\r' overwrites the output for each iteration.
• The value of time_sec is decremented at the end of each iteration.
