Becouse I can't : I do not know the partial WIF , if you know please share, and seconds there is only one output.
This is why I can't solve the famous puzzle. if you know math you should known that.
The principle is the same, there is a private key in a certain key range that we only know the corresponding address or public key. Whether it is a WIF missing characters or a puzzle with a key intentionally created in a certain range. The methods used for finding that key is the same too.
