@Fast-Nop If you are pro then obviously this would be a dumb question for you but I am a beginner and this question is not a dumb question for me.
And you are saying is again and again that this is a homework question so listen I am in 9 standard and I thought you know that programming is not taught in 9 standard. I was just trying a random question and when i fail to solve it , I just asked and i don't think so that i m doing something wrong

@Fast-Nop It is not necessary that if any one asking a question, it should be his/ her homework.And it would not have happened that as soon as you were born, you had become a pro in programming, you have struggled yourself, you must have taken the help of someone ok get this thing in yr mind.

And I am not like you that if I do not get any question then I should change my path.
