if we enter total matchstick as 4 then if user is picking 3 matchstick then this program will not wrk i guess
Hi Tulsi,
I think there is some rule with the game that the Number of matchsticks should be greater than or equal to 5
Actually if the total matchsticks are 4 then computer would play first as the if block in main method checks for.
I hope that explains your doubt.
