here in this program i am getting exception
when i try to take input 3 strings but i get only 2 string to input the value

Hey @ketushubham098,

Here i should be less than arr.length

#3

you havent read my doubt properly
my doubt is that my program is asking for the input n-1 times when i enter n inputs
for eg when i enter 3 i only get 2 inputs thats the problrm in my code

That is happening because you are using sc.nextLine() to take the input. Use sc.next() to take the string input.
And you are receiving the exception as Array Index Out of bounds.
To resolve that make the changes as suggested in my the previous message.
