In a make task you use the skills you have learned to create a program from scratch. There is no starter code: you begin with an empty editor.

This one is a rocket launch countdown. The counters you have written so far all counted up. This one counts down, which changes the starting value, the condition and the line that moves the counter, but nothing else.

Your task

Ask the user where the countdown should start, and store the answer in a counter variable. Ask the question with its own print, exactly as written:
```
Where should the countdown start?
```
Read the answer with a bare input() and wrap it in int() so that it is a number rather than text.
Use a while loop that keeps going for as long as the counter is greater than 0.
Inside the loop, print the counter, and then subtract 1 from it.
Once the loop has finished, print Blast off.

The output

The question is printed first, exactly as written above. Then your program prints the counter on a line of its own, once per repetition, from the starting value down to 1. Finally, after the loop, it prints exactly this:

Blast off

Nothing else is printed: no other words, and no blank lines.

The condition is checked before the body runs, every time. So if the user enters 0, or a negative number, the counter is not greater than 0 to begin with, the body never runs at all, and the whole output is the Blast off line. Your program does not need to treat that as a special case: a loop written correctly already does the right thing.

Example

Input:

Output:

Where should the countdown start?
5
4
3
2
1
Blast off

Input:

Output:

Where should the countdown start?
1
Blast off

Input:

Output:

Where should the countdown start?
Blast off

The question is part of the output that is checked here, so its spelling, capital letters and punctuation count. Ask it with its own print, exactly Where should the countdown start?, and read the answer with a bare input() on the next line, rather than passing the question to input(...).

Help! My code doesn't work!

Make sure that you check for the following things:

Iteration begins with while.
The while line has a condition.
The while line has a colon (:) at the end.
All the code you want to repeat is indented after the while, and all of it by the same amount. Never mix tabs and spaces in one file.
Any code that should run once the loop has finished is not indented, so Blast off is printed once rather than every time round the loop.
The counter goes down inside the loop, with counter = counter - 1 or the shorthand counter -= 1. A counter that goes up never reaches 0, so the loop would never end.
The input is wrapped in int(), or the counter is compared as text.
