Given a number such as 2639 return all possible string permutations using the phone-keyboard on Problem 1069.
input = 2639
output = {'amdw' 'amdx' 'amdy' ... 'andy' 'andz' ... 'body' 'bodz' ... 'cody' ... 'cofz'}
This solution which is leading solution is not correct when the input x is a single number. For example if x = 2 , you expect a,b,c instead you only return a
Thank you for your advice.
I correct it.
why the given result is in the format of cell,not char,why 'amdw'~='admw',which my matlab only give the latter,rather than the former one
