Answer 3

Your code is not SoloLearn compliant.
Edited it to be SoloLearn compliant:
https://code.sololearn.com/c8V8RyjkygmO/?ref=app

1. Removed hidden chars
2. Included std lib

However it still does not do console, so valid input must be given to terminate else runs forever. You can add a counter to stop.

Input in pop up:
2 8
5 4
1 20

Basically the infinite loop is not your fault but SoloLearn, since they do not support direct console input, like remote terminal I used before.

However as Jamie pointed out there still is some logic issues:
1. Do you want to loop until the number sum is or isn’t 21?
A. If so then you should use !=
B. However whether or not it should be 21, your logic will always display the losing (try again) message. Hence I added the if statement before the losing statement.

Keep up the good work!
