Question
Chapter 1, Problem 22C
Program Plan Intro
Strings formed by using characters
Program plan:
- Create a class Permute that displays all the possible strings formed by using the characters.
- In main() function,
- Declare the required variables.
- Create the object for the class permute.
- Use the object to invoke the method nextLevel().
- In nextLevel() method,
- Use the for loop to remove the remaining letters from string and then it is inserted into partial string.
- Call the function nextLevel().recursively to remove each letter one at a time from remainingLetters and then append it to the partial string.
- If there are no remaining letters, partial string must be completed and convert it to a string to display it.
- In main() function,
