Write the script to display a number in reverse order? Also specify the algorithm.

The algorithm for the above program would be:

- Ask the user to enter the number.

- Set the values of rev and sd as 0.

- Find the single digit that is the left most digit.

- Construct the new number as rev * 10 + sd

- Now the n has to be decremented by 1.

- In case n is greater then zero repeat the above steps from third step or else print the number.

The code for the above algorithm is:
