My solution for Chef and digits of a number.Please tell me why i am getting a WA.I have tried all kinds of inputs and the output seems to be correct.PLEASE HELP!!

Try this basic test case-

Input
1
1
Your Output
No
Expected Output
Yes (we can flip that 1 and get entire string 0)

Further, I heard that using goto statements isnt exactly a good programming practice.

3

Umm my IDE shows output Yes.Can you please check it again?

4

Its giving No in codechef IDE, due to this- else if(one==0 || zero==0){printf("No\n");}

5

My IDE uses gcc 7.0 beta version.Is it because of that?

6

Not sure, but try running and compiling it in codechef IDE.

7

The codechef IDE is messed up.I tried printing the value of “one” when my input string was only 1.it outputted 100000…
Printed the same value in my Dev C++ IDE and it outputs 1.

It means your code is messing up somewhere. Sometimes, the IDEs we use kind of spoonfeed us by automatically fixing some erros/behaving in a way that our error doesnt affect the procedure. I will have a more detailed look at your code (if you modified code, please give a link :slight_smile: )

EDIT- Did you remembered to give a new line character at the END of input? Because without it your logic fails since theres no newline char after string.

Small mistakes.

  1. Constraints on n = 10^5.
    But your input takes less than 10^5 chars,[ for( i = 0; i < 100000; i++) ],
    which should have been [ for( i = 0; i < (some number greater than 10^5); i++) ]

  2. Variable ‘total’ must have been initialized to 0.

Here is AC version after modifying your code.
