Phone keypad problem

#1

i am not able to get one test case right can you please help me with it

#2

@WARHEAD in line number 4, the 0th string has a space, it’s not an empty string, i.e, replace “” with a " ". And now, since we have to include the space in output array, remove the condition on line number 15 where you are checking whether the value of digit is 0 or not, and your code will work fine.
Hope this helps.
