Find the maximum number of towers with same color order that can be obtained from an initial group of tricolored towers if at most one swap of adjacent colors can be performed in every tower.

Happy Lunar New Year! 新年快樂! Gong Hei Fat Choy! Chúc Mừng Năm Mới!

The first 3 developers to solve the challenge perfectly in the least amount of time from the start of the challenge will be added to the Codility Hall of Fame and win a $25 Amazon gift card, which you can spend on a gift for your loved ones to welcome the Year of the Tiger.

Once the Year of the Tiger challenge has ended (on March 12th), you will still be able to take the challenge and gain certificates, but you will no longer be in the running for prizes.

Good luck solving this challenge!
