For example, for the string abc, the permutation isabcacbbacbcacabcba public static void displayPermutation(String s)public static void displayPermutation(String s1, String s2)The first method simply invokes displayPermutation(" ", s). The secondmethod uses a loop to move a character from s2 to s1 and recursively invokesit with new s1 and s2.
