could someone please point out the foolishness.

Abdujabbor Re: wrong answer in most tests. 1002.cpp [1] // Problem 1002. Phone Numbers 25 Aug 2014 01:13

this I think:

cout<<"no solution";

cout<<"No solution";

TravisGRivera Re: wrong answer in most tests. 1002.cpp // Problem 1002. Phone Numbers 22 Jun 2015 02:49

actually should be "No solution." remember the period.

Ashok Re: wrong answer in most tests. 1002.cpp // Problem 1002. Phone Numbers 8 Feb 2015 19:28

May be you should decrease the counter.
counter--;
as you are trying to compare
counter==0;

Another issue: Major one,
Your code is literally comparing the converted numbers directly to the input number. If no number is matched you have to check all the possible permutations of the converted number array.
The question is asking minimum number of words required to match the number. (GOT IT?)
