hey please give right link its not working.

3

are you using && for logical operator ‘and’ or as a bit-wise?

4

i am asking this because i am not familiar with c++ so much so please tell so that i can look it at and find what’s wrong because i have basic knowledge in c++ which you have used.

5

The first problem i see in the code is the method used for inputting the string. you need to give space between characters. Try using gets().
secondly, dropping the condition for N can be done and using instead ((ci || cy) == 0) should work.

Well, you have to input a string( characters without spaces ) but your code will input space separated integers. Better use the string data type.

Eg:

string s;

cin>>s;

Look at my code to understand the logic: http://www.codechef.com/viewsolution/7214260
