(Solved) : Jgrasp Java B04 Number String Permutation Write Program Ask User Number Compute Permutatio Q30121249 . . . .

JGRASP ONLY! (Java) B04 – Number/String permutation Write aprogram that will ask the user for a number, and then it willcompute the permutation of every digit in that number. You need arecursive method that will print all the permutations of thenumber.
For example, for the number 123, the permutation is:
123 132 213 231 312 321
Hint: Define two methods. The second is a helper method. publicstatic void permutation(String s) public static voidpermutation(String s1, String s2) The first method simply invokesdisplayPermutation(” “, s).The second method uses a loop to move acharacter from s2 to s1 and recursively invokes it with a new s1and
