n=21;

while(n>1)

{

printf("Enter numbers of matchsticks you want to pick up\n");

scanf("%d",&a);

n=n-a;

printf("Left matchsticks=%d\n",n);

b=5-a;     /* This is the trick you have to figure out,this will make eventually computer win*/

printf("Computer picks=%d\n",b);

n=n-b;

printf("Left matchsticks=%d\n",n);

}

if(n==1)

printf("You lost,Better luck next time :p\n");
