code forces FileList problem

Code forces FileList problem :

PseudoCode:
==============

#define MAX_FILENAME 8
#define TwoContinuousDots 0
#define SingleCharBetweenTwoDots 1
#define MAX_FILE_EXT 11
#define EndsWithDot 0
#define MAX_EXT 3

1.read the string input
2.Identify the dot & break the loop
3.if (stringBeginsWith == Dot) return NO;
4.if (CurrentCharPosition > MAX_FILENAME) //DotPosition exceeds
MAX_FILENAME allowed || Dot is not available within 8 character
return NO;
5.Store the ++LastDotPos
6.start loop through the string till EOS reached
7.if [ currentDotPos - lastDotPos == TwoContinuousDots ] { return NO;}
8.if ( CurrentDotPos - lastDotPos == SingleCharBetweenTwoDots ) { return NO;}
9.if ( CurrentDotPos - lastDotPos > MAX_FILE_EXT ) return NO;

At Last of the string,
10.if( CurrentDotPos - lastDotPos == EndsWithDot ) return NO;
11.if( CurrentDotPos - lastDotPos > MAX_EXT ) return NO; //Last
extension exceeds MAXIMUM_EXTENSION size
12.Yes... we are going to parse the valid String
13.create loop1... Search First Dot
14.if (char == FirstDOT) create loop2 and look for SecondDOT
15.if no second DOT and EOS reached,print string. [Ex: t.txt]
16.if(TwoDotsDiff <= MAX_EXT) printf( secondDot + 1 char);Move i by 1
17.else print (3 characters) Move i by 3
