Algorithm to Obtain the Number 47 from 7 Using the "Doubler" Program

To obtain the number 47 from the number 7 using the "Doubler" program, we need to write an algorithm that consists of a sequence of commands. The two available commands are:

1. Subtract 1 from the current number. 2. Multiply the current number by 2.

The goal is to find a sequence of commands that transforms the number 7 into the number 47, using no more than 5 commands.

To solve this problem, we can use a trial-and-error approach. We will start with the number 7 and apply different combinations of the two commands until we reach the number 47. Let's go through the process step by step:

1. Start with the number 7. 2. Multiply the number by 2: 7 * 2 = 14. 3. Multiply the number by 2 again: 14 * 2 = 28. 4. Subtract 1 from the number: 28 - 1 = 27. 5. Multiply the number by 2: 27 * 2 = 54. 6. Subtract 1 from the number: 54 - 1 = 53.

At this point, we have obtained the number 53, which is greater than 47. Since we are limited to a maximum of 5 commands, we cannot reach the number 47 using this approach.

Therefore, it is not possible to obtain the number 47 from the number 7 using the "Doubler" program with a sequence of no more than 5 commands.

Please note that this solution is based on a trial-and-error approach and there might be alternative algorithms or combinations of commands that could yield different results.
