TED-Ed: The Chasm | Think Like A Coder, Ep 6 | Alex Rosenthal

The video tutorial explains a challenge where characters must cross a ravine using hover blocks that form a stable bridge only if they are arranged in a palindromic sequence. It discusses the inefficiency of a naive solution and introduces a more efficient method to determine if a sequence can be a palindrome by analyzing the frequency of letters. The tutorial concludes with the characters' success in finding a solution, though not all are safe.
