The letters should be taken alternatively from each string. Assume that the length of
both the strings are the same.

Answer 1

Answer:

class A{

public static void main (String args[])

{

Scanner sc=new Scanner(System.in);

String str1=sc.nextLine();

String str2=sc.nextLine();

if(str1.length()==str2.length())

{

int flen=str1.length()+str2.length();

for(int i=0, int j=flen, int k=0; i<flen/2, j>=0,k<flen; i+2,j-2,k++)

{

arr[k]=str1.charAt(i);

k=k+1;

arr[k]=str2.charAt(i);

}

}

for(int i=0; i<flen: i++)

{

System.out.println(arr[i]);

}

}

}

Explanation:

I hope this should work....

Used the for loop with 3 variables...

flen is the summation of two string lengths...

Hope this solves....
