code show as below:

#include<stdio.h>

// if it is 1 plate
// Directly move the plate on master A to B with C
// else
// First move the n-1 plate on column A to B with the help of C
// directly move the plate on column A from A to C
// Finally, move the n-1 plates on the B column to C with the help of A
	if(n==1)

	else
