Generate all possible strings such that char at index i is either str1 [ i ] or str2 [ i ] | Java implementation of the approach.
Recursive function to generate the required strings.
If length of the current string is equal to the length of the given strings then the current string is part of the result.
Choosing the current character from the string a.
Choosing the current character from the string b.
Driver code.
Third argument is an empty string that we will be appended in the recursion calls Fourth arguments is the length of the resultant string so far"
How can the above be solved in Java?

#Here is code to generate all possible strings such that char at index i is either str1 [ i ] or str2 [ i ] and the other steps required.
 class GFG { public static void generateStr ( String a , String b , String s , int count , int len ) { if ( count == len ) { System . out . println ( s ) ; return ; } generateStr ( a . substring ( 1 ) , b . substring ( 1 ) , s + a . charAt ( 0 ) , count + 1 , len ) ; generateStr ( a . substring ( 1 ) , b . substring ( 1 ) , s + b . charAt ( 0 ) , count + 1 , len ) ; } public static void main ( String [ ] args ) { String a = " abc " , b = " def " ; int n = a . length ( ) ; generateStr ( a , b , " " , 0 , n ) ; } }
