2025 Winter Challenge: Quinindrome

A few months have passed and the first snowflakes have fallen since the end of the Synacktiv Summer Challenge. This event was a success, with one of the participants even finding a zero-day vulnerability while working on his solution! Although it hasn't been made public yet, it will be covered in an upcoming article on the Synacktiv website. As winter is coming, it's now time to introduce the Synacktiv Winter Challenge! Join other participants in this code golf contest and send us your solution before January 1st 🏌️.
