Please either format your code or (better!) link to your submission - the forum software has mangled it and it won’t compile! :slight_smile:

Thanks :slight_smile:

  1. N can be up to 25000, but you are only allocating space for N up to 20000; and
  2. |w_i| can be up to 5, and 5 chars is not enough space to hold a string of 5 characters read via scanf("%s", ...) due to the null-terminator.

Sir, now it showing time limit exceeded what to do know.

Come up with a faster approach :slight_smile:

Edit:

Your latest submission is giving the wrong answer for the sample testcase - I suggest fixing that, first.

@ssjgz you should keep this as your CC discuss template. XD
