Smart keypad 1 problem from recursion

#1

I don’t understand why it’s failing one case when it passes another?

Hey @div_yanshu07 you are not passing single test case because it consist of zero digit also. As it’s not mentioned in the question(fault by problem setter) . When you encountered 0 , you have to add a space just like you did for when you get 1. Right now you are just avoiding and not adding anything .
int digit=in[i]-‘0’;

if(digit==0)

{

   generateNames(in,out,i+1,j);

}
so make this small change that when you encounter 0 you add a space just like for 1
Do this and you will surely pass all test cases :smile:. Keep coding :+1:
