how can i generate string from num string?

@Vipin_coder,

you are printing all the strings given to you.

Suggested approach:

This problem is almost the same as in smart keypad 1 problem ,i.e,
String table[]= { " ", “.+@$”, “abc”, “def”, “ghi”, “jkl” , “mno”, “pqrs” , “tuv”, “wxyz” }.

So in this question you need to print those strings (from search In array) that contain the strings generated by the alphabetical combination of number given as the input
Ex:- 34
3 => d,e,f
4 => g,h,i
So print all those strings that contain these combinations
dg, dh, di, eg, eh, ei, fg, fh, fi.

Also you only need to print strings from these only
string searchIn [] = {
“prateek”, “sneha”, “deepak”, “arnav”, “shikha”, “palak”,
“utkarsh”, “divyam”, “vidhi”, “sparsh”, “akku”
};

for 102 combination are “. a” , “. b” , it will search for this ryt?

#4

@Vipin_coder,
For 1 we have ‘.+@$’ and for 2 we have abc. For 0 we have “”. Hence for 102 it will a combination of ‘.+@$’ and abc. So yes we will search for the 12 possible combinations

#5

but for 0 , there is space in question plz check it , " "

#6

@Vipin_coder,
It is " ". I misread it, but since it is a single char, the possible permutations will be ‘.+@$’, " " and abc

#7

then i m ryt or wrong?? for 102 combination are “. a” , “. b” , it will search for this ryt?

#8

@Vipin_coder,
No.

See, for 1 we have options: .+@$ ; for 0 we have options: " " ; for 1 we have options: abc

Now for 102 possible combinations will be:

. a
. b
. c
+ a
+ b
+ c
@ a
@ b
@ c
$ a
$ b
$ c
