A company is developing a new electronic watch for high-performance athletes. One of the features of the new watch is that it will measure the athlete's current heart rate (beats per minute) and current oxygen saturation. The watch will also calculate and store the athlete's resting heart rate.

The designers want the watch to warn the athlete that he or she must:

  • slow down the pace of exercise if the current heart rate is more than three times the resting heart rate OR the current oxygen saturation is less than 95;
  • increase the pace of exercise if the current heart rate is less than twice the resting heart rate AND the current oxygen saturation is greater than 97;
  • maintain the pace of exercise if none of the above conditions occur.

Given the resting heart rate, the current heart rate and the current oxygen saturation obtained by the watch, write a program that produces the suggestion that the Watch should emit.

Input: Three integers (int).

Output: Integer (slow down - -1, increase - 1, maintain - 0).


assert pace_adjust(60, 190, 98) == -1
assert pace_adjust(70, 140, 92) == -1
assert pace_adjust(70, 130, 98) == 1

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=py config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
