WebThe idea is to convert the given string to a character array, and in-placegenerate all its permutations using backtracking. We can do this by swapping each of the remaining characters in the string with its first character and generating all the permutations of the remaining characters using a recursive call. WebBacktracking is a general algorithm for finding all (or some) solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons each partial candidate c (“backtracks”) as soon as it determines that c cannot possibly be completed to a valid solution.
