Extracted text: Write a recursive method to print all the permutations of any string. For example, for the string abc: abc acb bac bca cab cba using two given methods: void displayPermutations(str) void displayPermutations (str1, str2) //helper Note: Helper method, uses a loop to move a character from str2 to stri and recursively invokes it with a new stri and str2. The base case is that str2 is empty and print stri to the console. //Assume no duplicate characters or space in the input string
