The number of moves required to solve the Hanoi tower is 2m + 1 . Therefore for a tower of five disks the minimum number of moves required is: 31.
The number of moves required to solve the Hanoi tower is 2m + 1 . Therefore for a tower of five disks the minimum number of moves required is: 31.
The least number of moves required to solve the Tower of Hanoi puzzle with 5 disks is calculated using the formula (2^n - 1), where (n) is the number of disks. For 5 disks, this results in (2^5 - 1 = 32 - 1 = 31) moves. Therefore, the minimum number of moves needed is 31.
RAID 1
The perfect score for the Tower of Hanoi game is determined by the minimum number of moves required to solve the puzzle. This number is calculated using the formula (2^n - 1), where (n) is the number of disks. For example, with three disks, the perfect score would be (2^3 - 1 = 7) moves. Therefore, the fewer disks there are, the lower the perfect score will be.
The most common RAIDs require between 2-4 drives.RAID0 requires a minimum of 2 drivesRAID1 requires a minimum of 2 drivesRAID5 requires a minimum of 3 drives.RAID10 requires a minimum of 4 drives.
The minimum number of moves required to solve the Tower of Hanoi puzzle with ( n ) disks is ( 2^n - 1 ). This formula arises from the fact that each disk must be moved at least once, and the recursive nature of the puzzle requires moving the smaller disks multiple times. Thus, for 3 disks, it takes 7 moves, and for 4 disks, it takes 15 moves, and so on.
To prove that (2^n - 1) gives the minimum number of moves required to solve the Tower of Hanoi problem for (n) disks, we can use mathematical induction. The base case, (n=1), requires 1 move, which matches (2^1 - 1 = 1). For the inductive step, assume that (2^k - 1) is the minimum for (k) disks. To solve for (k+1) disks, you move the top (k) disks (requiring (2^k - 1) moves), move the largest disk (1 move), and then move the (k) disks again (another (2^k - 1) moves), resulting in (2 \cdot (2^k - 1) + 1 = 2^{k+1} - 1), thus confirming the formula holds for (k+1) as well.
The total no. of disks that are required to make RAID 1 is 3
